Description

Technical Field

[0001] This invention relates to the field of transportation or storage devices, and more specifically to a high-low level transmission device to prevent battery tipping. Background Technology

[0002] In the battery manufacturing process, after the batteries are manufactured, they need to be transported in batches to the packaging workshop for subsequent boxing and packaging. Currently, the industry commonly uses AGVs (Automated Guided Vehicles) as the main conveying equipment for this stage, in order to achieve automated or semi-automated transfer of batteries between different processes.

[0003] However, existing AGVs still have many problems that need to be solved when they are used in conjunction with battery loading processes, as follows:

[0004] Firstly, in scenarios where AGVs are used in conjunction with manual battery loading, the batteries are placed one by one onto the AGVs by hand. This method is not only inefficient and unable to meet the pace requirements of large-scale production, but also requires workers to perform repetitive bending and placing actions for extended periods, resulting in high labor intensity, fatigue, and potentially affecting the standardization and consistency of operations. More importantly, during manual placement, the positioning and placement force of the batteries rely entirely on experience, making it highly susceptible to damage from improper operation, which could cause the batteries to collide with AGV components, potentially damaging the battery's appearance and internal structure.

[0005] Secondly, when AGVs are used in conjunction with conveyor belts to load batteries, the batteries are usually transferred directly from the conveyor belt to the AGV. Because there is a certain height difference between the conveyor belt and the AGV, a falling space is created. During this process, collisions with the AGV's load-bearing surface or the batteries already placed on it are inevitable, causing damage to the batteries and affecting product quality.

[0006] Furthermore, even if the batteries are successfully mounted on the AGV, the existing AGV's load-bearing structure lacks effective fixation for the arranged batteries. During the AGV's transport process, especially during start-up, stopping, and turning, the batteries will shift, shake, or even collide with each other due to inertia. This continuous collision not only further exacerbates the damage to the batteries but also adversely affects their electrical performance and safety, ultimately leading to a decrease in battery yield and increased production costs. Summary of the Invention

[0007] The present invention aims to provide a high-low position transmission device to prevent battery tipping, so as to solve the problem that when batteries are loaded by AGV carts in conjunction with manual labor or conveyor belts, the batteries are prone to tipping and bumping during high-low position transmission, which affects the battery yield and transmission efficiency.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A high-low position transmission device for preventing battery tipping includes a frame and an AGV trolley. A top-level conveying mechanism is mounted on the frame, and the AGV trolley is positioned below it. The top-level conveying mechanism includes a vertical lifting group and a conveyor belt. The conveyor belt receives batteries and vertically transports them to the vertical lifting group with their length and width as support surfaces. A straightening component is mounted on the conveyor belt to straighten tipped-over batteries. The vertical lifting group clamps the batteries and transports them to the AGV trolley. The vertical lifting group includes a lifting bracket with a feed inlet on its top side, which communicates with the conveyor belt. A conveyor disc is located inside the lifting bracket, and a lifting drive component is mounted on the lifting bracket to drive the conveyor disc up and down. The conveyor disc has an opening at the bottom with a horizontally opening movable base plate. A clamping component for holding the batteries is mounted on the base plate.

[0010] Preferably, as an improvement, the straightening component includes a mounting wall disposed on one side of the conveyor belt, a rotating central shaft rotatably connected to the mounting wall, and multiple arc-shaped baffles connected to the rotating central shaft. The multiple arc-shaped baffles are arranged along the conveying direction of the conveyor belt. The arc-shaped baffles can rotate to above the conveyor belt to block the conveying direction of the battery. When the arc-shaped baffles rotate to the conveyor belt, their concave surfaces face the direction of battery feeding. A single battery receiving space is formed between two adjacent arc-shaped baffles. The receiving space is used to accommodate a straightened battery.

[0011] Preferably, as an improvement, a rotating central shaft is connected to a rotating central shaft motor, and a detection element is provided on the conveyor belt. The detection element is used to detect whether the battery is tipped over. The detection element is electrically connected to a controller, and the controller is electrically connected to the rotating central shaft motor. An arc-shaped baffle is fixed with a sleeve, which is fitted onto the rotating central shaft. An electromagnetic clutch is connected between the sleeve and the rotating central shaft. The driving end of the electromagnetic clutch is fixedly connected to the rotating central shaft, and the driven end of the electromagnetic clutch is fixedly connected to the sleeve. The electromagnetic clutch is electrically connected to the controller.

[0012] 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.

[0013] Preferably, as an improvement, the two inflatable corrugated plates unfold in the same direction as the length of the battery. The clamping component is an inflatable protrusion located at one end of the two inflatable corrugated plates that is far apart from each other. The inflatable protrusion is connected to an air pump. After being inflated, the inflatable protrusion can expand towards the middle to clamp the battery.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] Preferably, as an improvement, the height of the side wall of the bottom tray is greater than the height of the battery.

[0018] Preferably, as an improvement, a guide limit plate is provided between the conveyor belt and the lifting support, and the guide limit plate is located on both sides of the feed inlet.

[0019] The beneficial effects of this plan are:

[0020] 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 7. The conveyor belt is equipped with rotatable arc-shaped baffles as a righting component. When a tipped-over battery is transported onto the conveyor belt, the arc-shaped baffle rotates to the top of the conveyor belt, using its concave surface to "catch" the battery. The conveying force of the conveyor belt allows the battery to climb up and reset along the arc surface of the baffle, thus righting the battery. This arrangement can accommodate battery tipping situations and eliminates the need for manual righting. In addition, multiple arc-shaped baffles are arranged along the conveyor belt's transport direction to handle scenarios involving continuously tipped-over batteries, ensuring uniform battery posture on the conveyor line, preventing tipped-over batteries from getting stuck or bumped in subsequent processes, and improving the stability of the conveyor route.

[0034] The present invention will be further described in detail below with reference to the embodiments.

[0035] Example 1

[0036] like Figure 1 and Figure 2 As shown, a high-low position transmission device for preventing battery tipping includes a frame 1 and an AGV trolley 2. A top-level conveying mechanism 3 is mounted on the frame 1, and the AGV trolley 2 is positioned below the top-level conveying mechanism 3. The top-level conveying mechanism 3 includes a vertical lifting assembly and a conveyor belt 4. The conveyor belt 4 receives the battery 30 and holds the battery 30 in a vertical position with its length and width as the support surface (i.e.,...). Figure 1 (As shown) the battery is conveyed to the vertical lifting group, which is used to clamp the battery 30 and convey it to the AGV trolley 2.

[0037] 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.

[0038] Combination Figure 3 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.

[0039] 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 transport direction of the battery 30. The clamping component is an inflatable protrusion 15 that is glued 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.

[0040] like Figure 1 As shown, a straightening component is installed on the conveyor belt 4. The straightening component is used to straighten overturned batteries 30. In actual use, batteries 30 conveyed on the production line may be like... Figure 1 The vertical state shown in the figure may also be such that the battery 30 is conveyed after being tilted forward or backward. This application provides a straightening component for such tilted batteries 30. Specifically, the straightening component includes a mounting wall 27 fixed to a frame 1 on one side of the conveyor belt 4. A rotating central shaft 28 is rotatably connected to the mounting wall 27, and multiple arc-shaped baffles 29 are rotatably connected to the rotating central shaft 28. A receiving space for a single battery 30 is formed between two adjacent arc-shaped baffles 29. The receiving space is used to accommodate a straightened battery 30. In this embodiment, there are four arc-shaped baffles 29. In actual use, the number of arc-shaped baffles 29 can be selected. The multiple arc-shaped baffles 29 are arranged along the conveying direction of the conveyor belt 4. The arc-shaped baffles 29 can rotate to cover the conveying direction of the battery 30 above the conveyor belt 4. When the arc-shaped baffles 29 rotate onto the conveyor belt 4, their concave surfaces face the direction of the incoming battery 30.

[0041] Combination Figure 4 and Figure 5As 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.

[0042] 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.

[0043] Working principle:

[0044] In actual use, the equipment is fixed on the production line at the battery 30 unloading position by the frame 1, so that the conveyor belt 4 is connected to the unloading end of the conveyor belt at the unloading position, and the battery 30 is directly transported onto the conveyor belt 4. The AGV trolley 2 drives to the bottom of the frame 1, so that a bottom tray 21 on it is aligned with the bottom of the lifting bracket 5 to receive the battery 30.

[0045] This embodiment takes the conveying of four batteries 30 at a time as an example. In actual use, the last arc-shaped baffle 29, that is, the arc-shaped baffle 29 near the lifting bracket 5, is rotated onto the conveyor belt, while the remaining arc-shaped baffles 29 are rotated vertically above the mounting wall 27 to avoid affecting the conveying of the batteries 30. Through the blocking effect of the lowered arc-shaped baffle 29, the four batteries 30 are conveyed sequentially to the arc-shaped baffle 29 and arranged close together. Then, the arc-shaped baffle 29 is lifted, and the conveyor belt 4 conveys 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, so that the two inflatable corrugated plates 12 are 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 thick rubber material to ensure the support effect, and shallow friction textures can be set on the surface to improve friction. After the battery 30 is delivered onto the inflatable corrugated plate 12, the inflatable protrusions 15 on both sides are inflated. After the two inflatable protrusions 15 are inflated, they expand towards the middle and thus press against the battery 30, thereby clamping the battery 30.

[0046] 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.

[0047] 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 moves out from under the frame 1, transporting the batteries 30 to the packaging workshop for packaging. The next empty AGV trolley 2 then moves under the frame 1 to load the subsequent batch of batteries 30.

[0048] In practical application, if a tipped-over battery 30 is transported, an arc-shaped baffle 29 is manually lowered. Under the conveying action of the conveyor belt 4, the tipped-over battery 30 is pressed against the arc surface of the arc-shaped baffle 29 and can slowly rise along the arc surface, thereby righting the battery 30. If a series of batteries 30 tip over, the arc-shaped baffles 29 can be lowered sequentially from the back (near the side of the lifting bracket 5) to the front. After the first transported battery 30 is righted, an arc-shaped baffle 29 on the front side is lowered to right the next battery 30.

[0049] Example 2

[0050] The difference between this embodiment and Embodiment 1 is that the unfolding direction of the inflatable corrugated plate 12 can also be perpendicular to the length direction of the battery 30, that is, the inflatable corrugated plate 12 in Embodiment 1 is rotated 90°. In this case, the two inflatable protrusions 15 are located in the conveying direction of the battery 30. However, when the two inflatable protrusions 15 are not inflated, they are attached to the surface of the inflatable corrugated plate 12, so they do not affect the conveying of the battery 30. The inflatable corrugated plate 12 is installed in the manner described in this embodiment. Since the free end of the inflatable corrugated plate 12 is connected to the support rod 14 for support, and the inflatable corrugated plate 12 is made of a relatively thick rubber material, it can still achieve stable support for the battery 30.

[0051] Example 3

[0052] The difference between this embodiment and embodiment 1 is that the rotating central shaft 28 is connected to a rotating central shaft motor, an industrial camera is installed on the conveyor belt 4, the industrial camera is electrically connected to a controller, and the controller is electrically connected to the rotating central shaft motor; an arc-shaped baffle 29 is fixed with a sleeve, the sleeve is fitted on the rotating central shaft 28, an electromagnetic clutch is connected between the sleeve and the rotating central shaft 28, the driving end of the electromagnetic clutch is fixedly connected to the rotating central shaft 28, the driven end of the electromagnetic clutch is fixedly connected to the sleeve, and the electromagnetic clutch is electrically connected to the controller.

[0053] In this embodiment, an industrial camera can detect an overturned battery 30, and when the overturned battery 30 is transported over, a signal is sent to the controller, which controls the rotating central shaft motor to rotate and automatically lower the arc-shaped baffle 29.

[0054] When multiple overturned batteries 30 are transmitted in succession, the controller can control the corresponding number of arc-shaped baffles 29 to be lowered. For example, when two overturned batteries 30 are transmitted in succession, the industrial camera first detects the first battery 30 and sends a signal to the controller. At this time, the controller first controls the electromagnetic clutch at the arc-shaped baffle 29 closest to the lifting bracket 5 (hereinafter referred to as arc-shaped baffle 29 No. 1, and from the lifting bracket 5 forward, they are referred to as arc-shaped baffle 29 No. 1, arc-shaped baffle 29 No. 2, arc-shaped baffle 29 No. 3 and arc-shaped baffle 29 No. 4). After the electromagnetic clutch is energized, its driving end and driven end engage. Then the controller controls the rotating central shaft motor to drive the rotating central shaft 28 to rotate. Since the electromagnetic clutches at the other arc-shaped baffles 29 are not energized, their driving end and driven end do not engage. Therefore, these arc-shaped baffles 29 cannot rotate with the rotating central shaft 28. Only arc-shaped baffle 29 No. 1 rotates with the rotating central shaft 28, thereby automatically lowering arc-shaped baffle 29 No. 1 to right the first overturned battery 30. When the second flipped battery 30 is transmitted, the controller only controls the electromagnetic clutch at the No. 2 arc baffle to be energized. At this time, only the No. 2 arc baffle rotates with the rotating central shaft 28, thereby lowering the No. 2 arc baffle 29 to right the second flipped battery 30.

[0055] Example 4

[0056] like Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that there is a guide limiting plate 31 between the conveyor belt and the lifting bracket, and the guide limiting plate 31 is located on both sides of the feed inlet 7. The guide limiting plate 31 can restrict the position of the battery 30 from the left and right sides, so that the battery 30 can be smoothly transferred to the conveyor plate 6.

[0057] The above descriptions are merely embodiments of the present invention, and common knowledge such as specific technical solutions and / or characteristics are not described in detail here. 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. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
