[0002] In a lithium battery automatic production line, the feeding rack is mainly used to automatically convey lithium battery cells to the processing stations for assembly. However, the existing feeding racks generally use manipulators to grab lithium battery cells to the processing stations. The reciprocating movement path of the manipulators is relatively long, resulting in slow feeding speed. Moreover, when facing double stations, if only a single manipulator is used for feeding operations at two processing stations, the feeding speed is even slower. And using two manipulators will have the problem of higher costs. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a feeding rack for a lithium battery automatic production line, which solves the technical problems of slow feeding speed of the existing feeding rack and difficulty in matching double-station feeding operations.

[0004] To solve the above technical problems, the utility model provides the following technical solutions: A feeding rack for a lithium battery automatic production line, including a mounting frame. A material bin is fixedly arranged on the top of the mounting frame. Below the material bin, there is a feeding mechanism for continuously conveying battery cells to two groups of processing stations. The feeding mechanism is installed at the bottom of the mounting frame. Behind the feeding mechanism, there are two groups of inclined guide frames fixedly arranged at the rear of the mounting frame.

[0005] The feeding mechanism includes a driving component installed at the bottom of the mounting frame. A rotating shaft is fixedly connected to the driving component. A dividing block is fixedly arranged on the rotating shaft directly below the material bin. The rotating shaft is rotatably connected in a bearing seat. The bearing seat is installed at the bottom of the mounting frame through a support frame.

[0006] Preferably, the bottom of the material bin is of a conical structure and is provided with an opening adapted to the size of the lithium battery.

[0007] Preferably, the driving component includes a motor installed at the bottom of the mounting frame. A turntable is fixedly arranged on the output shaft of the motor. A push block is fixedly arranged at a position near the edge of the side wall of the rotating shaft. The push block is slidably arranged in a strip-shaped hole opened on a T-shaped tooth plate. The top of the T-shaped tooth plate is sleeved on a guide rod. The guide rod is fixedly connected to the front of the mounting frame. A gear is meshed with the T-shaped tooth plate. The gear is fixedly connected to one end of the rotating shaft.

[0008] Preferably, the top of the dividing block is an arc surface and is provided with a material groove adapted to the size of the lithium battery.

[0009] Preferably, a notch is provided on one side of the top of the guide frame close to the dividing block.

[0010] Preferably, a mounting plate is fixedly provided at the bottom of the material guiding frame, and the mounting plate is mounted on the inner side of the mounting frame by bolts.

[0011] Preferably, a fixing frame is fixedly provided on the front surface of the mounting frame, and two cylinders facing the notch positions are mounted on the fixing frame.

[0012] With the above technical solutions, the present utility model provides a loading rack for a lithium battery automatic production line, which at least has the following beneficial effects:

[0013] 1. For the loading rack of the lithium battery automatic production line, by setting the feeding mechanism, the driving component works to drive the distributing block to swing, and the battery cells fall from the bottom of the material bin into the material grooves on the distributing block.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] A lithium battery is a type of battery in which the key chemical substance is lithium. A lithium battery usually consists of one or more units called battery cells, and each unit includes a positive electrode, a negative electrode, an electrolyte, and a separator. Through chemical reactions, a lithium battery can store and release electrical energy. Lithium batteries usually use lithium ions or lithium polymers as electrolytes and are commonly used in mobile electronic devices (such as mobile phones, laptops), power tools, electric vehicles, and other applications. Due to its high energy density, lightweight, fast charging, and other characteristics, lithium batteries have been widely used in modern society.

[0024] Based on the technical defects of slow feeding speed and difficulty in matching double-station feeding operations existing in the prior art, please refer to Figures 1-4 , a feeding rack of a lithium battery automatic production line provided by the present utility model can continuously feed battery cores into two guiding racks 4 respectively, and then convey them to the processing stations through the guiding racks 4. Compared with the feeding method by a robotic arm, it can continuously perform feeding work, with a fast feeding speed and is suitable for double-station processing operations. It includes a mounting frame 1, a material bin 2 is fixedly arranged on the top of the mounting frame 1, a feeding mechanism 3 for continuously conveying the battery cores to two groups of processing stations is arranged below the material bin 2, the feeding mechanism 3 is installed at the bottom of the mounting frame 1, and two groups of inclined guiding racks 4 are arranged behind the feeding mechanism 3, and the guiding racks 4 are fixedly arranged behind the mounting frame 1; during feeding, the feeding mechanism 3 swings and drives the battery core to move to one side, and under the action of the air cylinder 8, the battery core is pushed into the guiding rack 4, and then the battery core rolls along the guiding rack 4 to the processing station.

[0025] To achieve single-piece separate feeding of the battery cores, please refer to Figure 1 and Figure 2 , the feeding mechanism 3 includes a driving component 31 installed at the bottom of the mounting frame 1, a rotating shaft 32 is fixedly connected to the driving component 31, a material dividing block 33 located directly below the material bin 2 is fixedly arranged on the rotating shaft 32, the rotating shaft 32 is rotatably connected in a bearing seat 34, and the bearing seat 34 is installed at the bottom of the mounting frame 1 through a support frame 35; by using the driving component 31 to work and drive the material dividing block 33 to rotate, since a material groove 331 is provided on the material dividing block 33, the battery cores can directly enter the material groove 331 after falling from the material bin 2, and then move to one side along with the swing of the material dividing block 33. Since only one battery core can be accommodated in the material groove 331 each time, single-piece feeding of the battery cores is achieved.

[0026] To ensure that the battery cells can fall smoothly from the bin 2, the bottom of the bin 2 is of a conical structure and is provided with an opening adapted to the size of the lithium battery; the conical structure ensures that all the battery cells can fall from the opening at the bottom.

[0027] To ensure that the material distribution block 33 can swing reciprocally continuously, please refer to Figure 2 , the driving assembly 31 includes a motor 311 installed at the bottom of the mounting frame 1. A turntable 312 is fixedly provided on the output shaft of the motor 311. A push block 313 is fixedly provided at a position near the edge on the side wall of the rotating shaft 32. The push block 313 is slidably arranged in a strip-shaped hole formed in a T-shaped toothed plate 314. The top of the T-shaped toothed plate 314 is sleeved on a guide rod 315. The guide rod 315 is fixedly connected to the front of the mounting frame 1. A gear 316 is engaged with the T-shaped toothed plate 314. The gear 316 is fixedly connected to one end of the rotating shaft 32; by driving the turntable 312 to rotate with the motor 311, the turntable 312 drives the push block 313 to make a circular motion. Under the action of the push block 313, the T-shaped toothed plate 314 can be driven to move reciprocally. The T-shaped toothed plate 314 can drive the material distribution block 33 to swing reciprocally through the engagement with the gear 316.

[0028] To realize the single feeding of the battery cells, the top of the material distribution block 33 is of an arc surface and is provided with a material groove 331 adapted to the size of the lithium battery; the arc surface can be attached to the bottom of the bin 2 to prevent the leakage of excess battery cells, and the material groove 331 can only accommodate one battery cell. Therefore, every time the material distribution block 33 swings, one battery cell can be separated and fed separately.

[0029] To ensure that the battery cells can be pushed into the guide frame 4, a notch 41 is provided on one side of the top of the guide frame 4 close to the material distribution block 33; after the position of the material groove 331 is aligned with the notch 41, the cylinder 8 can run smoothly to push the battery cells into the guide frame 4.

[0030] To facilitate the installation of the guide frame 4, a mounting plate 5 is fixedly provided at the bottom of the guide frame 4. The mounting plate 5 is installed on the inner side of the mounting frame 1 through bolts 6; the guide frame 4 can be fixed behind the mounting frame 1 by using the mounting plate 5 and the bolts 6.

[0031] To smoothly push the battery cells out of the material groove 331, a fixed frame 7 is fixedly provided on the front of the mounting frame 1. Two groups of cylinders 8 are installed on the fixed frame 7 opposite to the position of the notch 41; when the material distribution block 33 swings to one side, the material groove 331 is just aligned with the notch 41 position of the guide frame 4. At this time, by extending the cylinder 8, the battery cells can be smoothly pushed into the guide frame 4.

[0032] As can be seen from the above embodiments, during feeding, under the action of the feeding mechanism 3, the motor 311 drives the turntable 312 to rotate, and the turntable 312 drives the push block 313 to perform circular motion. Under the action of the push block 313, the T-shaped toothed plate 314 can be driven to reciprocate. The T-shaped toothed plate 314 can drive the material distribution block 33 to swing reciprocally through meshing with the gear 316. When the material distribution block 33 moves to the middle position, the material groove 331 just corresponds to the opening at the bottom of the material bin 2, and a single battery cell directly falls into the material groove 331. Then the material distribution block 33 swings to one side. At this time, the material groove 331 just aligns with the notch 41 of the material guiding frame 4. By extending the air cylinder 8, the battery cell can be smoothly pushed into the material guiding frame 4, and then the battery cell rolls along the material guiding frame 4 to the processing station.
