Description
Technical Field
[0001] This utility model relates to the field of auxiliary equipment for battery production, specifically to an automatic battery unloading machine. Background Technology
[0002] After production, cylindrical batteries are typically arranged neatly in plastic trays, each holding dozens to hundreds of batteries for easy transport and temporary storage. Currently, the packaging process generally relies on operators manually removing each battery one by one from the tray's slots and placing them into packaging boxes or battery slots. This manual method has significant drawbacks: firstly, the process is time-consuming and labor-intensive, inefficient, and difficult to match the production pace of high-speed automated production lines, easily creating production bottlenecks; secondly, as production scales up, the demand for manpower continues to increase, not only driving up labor costs but also increasing management difficulty and the risk of human error, such as incorrect battery polarity placement or scratches on the surface. Furthermore, prolonged repetitive operations can easily lead to worker fatigue, affecting work consistency. Therefore, traditional manual operations are no longer suitable for the modern battery industry's requirements for high efficiency, low cost, and high consistency; achieving automated and intelligent battery handling has become a key aspect of improving quality and efficiency in the industry.

The tray flipping mechanism 3 and the tray translating mechanism 8 are installed at the front end of the frame 1. The mechanism includes a tray lifting mechanism 4, a battery suction mechanism 5, a battery conveying mechanism 6, and a battery conveying mechanism 7. The tray flipping mechanism 3 is located in front of the first tray conveying mechanism 2. The tray flipping mechanism 3 drives the flat tray to flip and turn it into a vertical position. The tray translation mechanism 4 drives the vertically placed tray to transfer from the tray flipping mechanism 3 to the tray lifting mechanism 5. The tray lifting mechanism 5 is located in front of the second tray conveying mechanism 8. The tray lifting mechanism 5 drives the tray to rise and approach the battery suction mechanism 6. The battery suction mechanism 6 sucks out the batteries in the tray and transfers them to the battery conveying mechanism 7.
[0016] like Figure 2As shown, the frame 1 has a full tray station A on one side and an empty tray station B on the other side. The full tray station A is used to place the tray 9 filled with batteries, and the empty tray station B is used to place the empty tray after the batteries have been removed.

[0019] like Figure 5 As shown, the material tray translation mechanism 4 includes a track plate 41, rollers 42, a push cylinder 43 and a push plate 44. The track plate 41 is located in front of the flip plate 32. Multiple rollers 42 are installed in the track plate 41. The push cylinder 43 is installed on the side of the track plate 41. The push cylinder 43 drives the push plate 44 to push the material tray 9 along the rollers 42 to the material tray lifting mechanism 5.
[0020] like Figure 6 and 7 As shown, the material tray lifting mechanism 5 includes a base plate 51, a fixed plate 52, a rotating shaft 53, a sprocket 54, a chain 55, a lifting motor 56, a synchronous belt transmission assembly 57, and a lifting plate 58. The base plate 51 is fixedly installed at the bottom of the frame 1. There are two fixed plates 52 installed on the base plate 51, spaced apart. A limiting plate 59 is installed in front of the fixed plate 52 to prevent the material tray from tipping over during the lifting process. Multiple rotating shafts 53 are installed between the two fixed plates 52 from bottom to top. Two sprockets 54 are installed on both sides of each rotating shaft 53. One chain 55 is driven to the sprockets 54 on the same side of different rotating shafts. The lifting motor 56 drives one of the rotating shafts to rotate through the synchronous belt transmission assembly. The lifting plate 58 is installed between the two chains 55, and the lifting plate 58 carries the material tray to gradually rise. Specifically, the rotating shaft 53 is divided into a first rotating shaft, a second rotating shaft, and a third rotating shaft. The first rotating shaft is located at the lower part of the fixed plate, while the second and third rotating shafts are located at the upper part of the fixed plate. The second and third rotating shafts are on the same horizontal plane, so that when the material tray is lifted to the top, it will switch from vertical to horizontal to facilitate subsequent handling.
[0021] like Figure 8 and 9As shown, the battery conveying mechanism 7 includes a conveyor plate 71, a conveyor belt 72, and a conveyor motor 73. The conveyor plate 71 is installed in the frame 1 and located in the middle of the lifting mechanism 5. The conveyor belt 72 is rotatably installed in the conveyor plate 71.

The battery suction mechanism 6 includes a mounting frame 61, an electric cylinder mounting plate 62, an electric cylinder 63, an L-shaped plate 64, a magnet (not shown), a guide seat 65, a guide rod 66, a push plate 67, and a limiting block 68. The mounting frame 61 is located in front of the conveyor plate 71. The electric cylinder mounting plate 62 is installed on the mounting frame 61. The electric cylinder 63 is installed in the electric cylinder mounting plate 62. The electric cylinder 63 drives the L-shaped plate 64 to move back and forth. A magnet is installed at the end of the L-shaped plate 64. The iron is close to the push plate 67. Guide seats 65 are installed at both ends of the L-shaped plate 54. Guide rods 66 are installed inside the guide seats 65. The rear end of the guide rods 66 is connected to the push plate 67. Limiting blocks 68 are installed on the mounting frame 61. The limiting blocks 67 face the guide rods 66. When the L-shaped plate 54 moves backward, the L-shaped plate 54 pushes the push plate 67 to move closer to the material tray. Due to the action of the magnet, the push plate 67 will attract the battery. At the same time, due to the action of the magnet, when the L-shaped plate 64 moves forward, it attracts the push plate 67 to move forward. When the L-shaped plate 64 moves forward, it takes the battery out of the material tray and moves to the conveyor belt 72. After the L-shaped plate 64 moves forward to the position, the limiting blocks 68 push the guide rods 66 to prevent the push plate from moving forward. The L-shaped plate 64 is detached from the push plate 67, the battery is no longer attracted, and the battery is transferred from the material tray to the conveyor belt.
[0022] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be considered that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the protection scope of the present utility model.
