Description

Technical Field

[0001] This utility model relates to the field of transportation or storage devices, specifically to a battery batch-cycle conveying device. Background Technology

[0002] In the battery manufacturing process, batteries need to be transferred between different workshops or sites. For example, after the batteries are manufactured, they need to be transferred to the packaging workshop for packaging and boxing. Currently, the industry commonly uses AGVs (Automated Guided Vehicles) for batch transfer of batteries. However, existing AGVs have the following problems when loading batteries: Due to the lack of effective fixation of batteries in the load-bearing structure of existing AGVs, during the transport process of the AGVs, especially during start-up, stopping, and turning, the batteries will shift, shake, or even collide with each other due to inertia. This will adversely affect the electrical performance and safety of the batteries, ultimately leading to a decrease in battery yield. Utility Model Content

[0003] The present invention aims to provide a battery batch cyclic conveying device to solve the problem in the prior art that batteries are prone to collisions during the conveying process, which affects battery quality.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A battery batch circulating conveying device includes an AGV trolley. The AGV trolley includes a compartment with an open top. AGV drive wheels are set at the four corners of the compartment bottom. A central shaft is rotatably mounted in the center of the compartment. Multiple bottom trays with a certain depth and an open top are arranged around the central shaft. The bottom trays are arranged in an array around the central shaft. A transmission mechanism connects the central shaft and the bottom trays. The central shaft is connected to a central shaft motor, which drives the central shaft to rotate. When the central shaft rotates, it can drive the bottom trays to rotate sequentially through the transmission mechanism.

[0006] Preferably, as an improvement, the transmission mechanism includes multiple guide rods fixed on the spindle, a central shaft fixed in the middle of the bottom of the bottom tray, and a square guide rail located at the bottom of the carriage with the spindle as the center. The guide rods have strip-shaped guide holes along their length direction, and the central shaft slides through the guide holes on the guide rods and is slidably connected to the guide rail at its bottom end.

[0007] Preferably, as an improvement, an air cushion is provided on the inner side of the side wall of the bottom tray, and the air cushion is connected to an air pump.

[0008] Preferably, as an improvement, a flexible protective pad is provided on the inner bottom surface of the bottom tray.

[0009] Preferably, as an improvement, the height of the side wall of the bottom tray is greater than the height of the battery.

[0010] The principles and advantages of this scheme are:

[0011] 1. This solution uses multiple base trays inside the vehicle to partition the batteries, effectively preventing collisions between large numbers of batteries. Furthermore, this partitioned placement method can accommodate multiple batches of batteries being loaded on the production line. A batch of batteries is loaded onto one base tray. After one tray is full, the rotating axle drives another empty base tray to the loading position to continue loading batteries. Once all the base trays of an AGV are loaded, the AGV drives away, and another empty AGV moves in to fill the gap. This allows for continuous battery loading and improves battery loading efficiency.

[0012] 2. This solution adopts a transmission mechanism consisting of guide slide rods, guide holes, guide rails, and a central shaft. When the shaft disc rotates, it can smoothly drive the bottom tray to rotate, ensuring the stability of the loaded batteries and preventing the batteries from being bumped or knocked during the loading process.

[0013] 3. This solution incorporates a protective pad on the inner bottom wall of the base tray and an inflatable pad on the inner side wall. This effectively absorbs vibrations during AGV movement, further preventing damage to the batteries within the base tray. Additionally, the inflatable pad on the inner side wall allows for adjustable inflation to press the battery sides firmly, improving battery stability and preventing loosening and subsequent impacts. In practical applications, the inflation level of the pad can be adjusted according to the battery model, thus securing different battery types and expanding its applicability.

[0014] 4. The top opening of the bottom tray facilitates battery loading, whether manually or automatically. The height of the bottom tray's sidewalls exceeds the height of the battery, ensuring the battery is fully contained within the tray and further improving battery stability.

[0018] The following detailed description illustrates the specific implementation method:

[0019] Example

[0020] like Figure 1 and Figure 2 As shown, the battery batch circulating conveying device includes an AGV trolley, which has a top-opening compartment 1 with AGV drive wheels 2 installed at the four corners of the bottom. A central hub 5 is rotatably mounted at the bottom center of the compartment 1. Multiple bottom trays 3 of a certain depth are arranged circumferentially on the hub 5. Preferably, the height of the sidewall of the bottom tray 3 is greater than the height of the battery to stably load the battery. 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 3. An inflatable pad 4 is glued to the inner sidewall of the bottom tray 3, and the inflatable pad 4 is connected to an air pump, which is installed outside the compartment 1. Each inflatable pad 4 is connected to the air pump via an air pipe. A cable tray is provided at the bottom of the bottom tray 3 to accommodate the air pipe. Each inflatable pad 4 has a valve on its air pipe to individually control the inflation and deflation of the inflatable pad 4 on a single bottom tray 3. The compartment 1 is equipped with a switch to individually control the opening and closing of each valve.

[0021] In practical applications, the number of bottom trays 3 can be selected. This embodiment uses eight bottom trays 3 as an example. The eight bottom trays 3 are arranged in an array around the central disc 5. A transmission mechanism connects the central disc 5 and the bottom trays 3. The central disc 5 is connected to a central disc motor, which drives the central disc 5 to rotate. The rotation of the central disc 5 can drive the bottom trays 3 to rotate sequentially through the transmission mechanism. The transmission mechanism includes eight guide rods 7 fixed on the central disc 5 (the number of guide rods 7 is the same as the number of bottom trays 3). The guide rods 7 have strip-shaped guide holes 6 along their length. A central shaft 9 is fixed in the middle of the bottom of each bottom tray 3. A square guide rail 8 is installed at the bottom of the carriage 1 around the central disc 5. The eight central shafts 9 slide through the guide holes 6 on the corresponding guide rods 7 and their bottom ends slide in the guide rail 8.

[0022] Working principle:

[0023] In practical applications, multiple batteries are grouped together and loaded into the base tray 3. The number of batteries in a group matches the size of the base tray 3, which can be customized according to the number of batteries to be loaded. During loading, batteries are first loaded into one base tray 3. After loading, the air cushion 4 is inflated, expanding and clamping the batteries securely within the base tray 3. Once one base tray 3 is loaded, the spindle motor drives the spindle 5 to rotate at a certain angle. The spindle 5, through the guide slide 7 and the central shaft 9, rotates all the base trays 3 at a certain angle, thus moving the next empty base tray 3 to the battery loading position for continued loading. This process is repeated until all base trays 3 are loaded with batteries. The AGV then moves away from the battery loading position, and the next empty AGV moves to the loading position to continue loading batteries, achieving continuous battery loading. Because the base tray 3 has protective pads on its bottom wall and air cushions 4 on its inner side wall, the batteries remain stable during transport, effectively preventing damage from impacts.
