Technical Field

[0001] The utility model relates to the technical field of lithium battery production and assembly equipment, and particularly relates to a lithium battery production and assembly device. Background Technique

[0002] A lithium battery is a type of battery with lithium metal or lithium alloy as the positive / negative electrode material and using a non-aqueous electrolyte solution. It is different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high requirements for the environment. Therefore, lithium batteries have not been applied for a long time. With the development of microelectronics technology at the end of the 20th century, the number of miniaturized devices has increased day by day, putting forward very high requirements for power sources. As a result, lithium batteries have entered the large-scale practical stage.

[0003] Generally, when processing lithium batteries, the positive and negative electrode materials are first wound together, and then the wound positive and negative electrode materials are installed in the outer shell, and welding and electrolyte injection are carried out. Among them, when assembling the inner core and the outer shell, it is usually completed by manual operation, so the production efficiency is limited. Content of the Utility Model

The horizontal linear motor drives a sliding table on which a vertical linear motor is installed. The sliding table of the vertical linear motor is connected with a U-shaped frame. The inner cavity of the U-shaped frame contains an outer shell with an assembly hole. On the top of the table body, on the side opposite to the vertical plate, a raw material bin is installed. Inside the raw material bin, a material placement cavity and a material feeding cavity that are connected are formed. On the side of the raw material bin close to the vertical plate, a guiding tube communicating with the end of the material feeding cavity is opened. On the side of the raw material bin far from the vertical plate, a cylinder with an output shaft that can extend into the guiding tube is installed.

[0006] Further, a feeding port is opened on one side of the top of the raw material bin.

[0007] Further, the bottoms of the material placement cavity and the material feeding cavity are both inclined.

[0008] Further, a guiding hole communicating with the material feeding cavity is opened on the top of the raw material bin, and a blocking rod that can be lifted and lowered and whose end can extend into the material feeding cavity is provided in the guiding hole.

[0009] Further, a fixing plate is fixedly connected to the top of the raw material bin. A turntable driven by a motor is rotatably connected to the fixing plate. An eccentric convex shaft is provided on the turntable. The top end of the blocking rod passes through the guiding hole and is connected to a strip-shaped frame provided with a strip-shaped groove.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to 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.

[0017] Please refer to Figures 1-3, the present utility model discloses a lithium battery production and assembly device, including a table body 1. One side of the top of the table body 1 is fixedly connected with a vertical plate 2. The top of the vertical plate 2 is equipped with a horizontal linear motor 3. The horizontal linear motor 3 drives a sliding table on which a vertical linear motor 4 is installed. The sliding table of the vertical linear motor 4 is connected with a U-shaped frame 5. An outer shell 6 with an assembly hole 7 is placed in the inner cavity of the U-shaped frame 5. On the top of the table body 1, on the side opposite to the vertical plate 2, a raw material bin 8 is installed. Inside the raw material bin 8, a material placement cavity 10 and a feeding cavity 11 that are connected to each other are formed. On the side of the raw material bin 8 close to the vertical plate 2, a guiding tube 13 that communicates with the end of the feeding cavity 11 is opened. On the side of the raw material bin 8 far from the vertical plate 2, a cylinder 12 with an output shaft that can extend into the guiding tube 13 is installed.

[0018] On one side of the top of the raw material bin 8, a feeding port 9 is opened.

[0019] Specifically, the bottoms of the material placement cavity 10 and the feeding cavity 11 are both inclined.

[0020] In this implementation scheme, the inner core in the material placement cavity 10 can enter the feeding cavity 11. Under the action of the cylinder 12, it is sent into the assembly hole 7 opened in the outer shell 6 from the guiding tube 13. Then, the outer shell 6 moves to the next working station for the welding operation of the inner core.

[0021] Specifically, on the top of the raw material bin 8, a guiding hole 21 that communicates with the feeding cavity 11 is opened. A blocking rod 20 whose end can extend into the feeding cavity 11 is installed in the guiding hole 21 in a liftable manner.

[0022] On the top of the raw material bin 8, a fixed plate 16 is fixedly connected. A turntable 17 driven by a motor is rotatably connected to the fixed plate 16. An eccentric convex shaft 19 is provided on the turntable 17. The top end of the blocking rod 20 passes through the guiding hole 21 and is connected with a strip-shaped frame 18 provided with a strip-shaped groove. The convex shaft 19 passes through the strip-shaped groove opened in the strip-shaped frame 18.

[0023] In this implementation scheme, when the motor drives the turntable 17 to rotate, the convex shaft 19 can be driven to rotate. During the rotation of the convex shaft 19, it can contact the inner wall of the strip-shaped groove to drive the strip-shaped frame 18 to lift, and then the blocking rod 20 can be lifted and lowered in the guiding hole 21. When the bottom end of the blocking rod 20 extends into the feeding cavity 11, it can block the inner core, so that the inner core in the material placement cavity 10 no longer moves into the feeding cavity 11. When the bottom end of the blocking rod 20 moves into the guiding hole 21, the inner core in the material placement cavity 10 moves into the feeding cavity 11.

[0024] Specifically, an electric push rod 14 is installed on the top of the U-shaped frame 5. The output shaft of the electric push rod 14 extends into the inner cavity of the U-shaped frame 5 and is connected with a limiting plate 15.

[0025] In this embodiment, the electric push rod 14 is located at the end of the top of the U-shaped frame 5, and the electric push rod 14 cooperates with the limit plate 15 to limit the housing 6 on the U-shaped frame 5.

[0026] In summary, for the lithium battery production and assembly device, the inner core in the raw material bin 8 can enter the feeding cavity 11, and is sent into the assembly hole 7 opened in the housing 6 from the guide tube 13 by the cylinder 12, and the loading of the inner core does not require manual operation.

[0027] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
