Description

Technical Field

[0001] This utility model belongs to the field of battery manufacturing technology, and specifically relates to a battery preheating device. Background Technology

[0002] In the battery production process, the use of a preheating device is indispensable to ensure the smooth progress of subsequent battery processing and the stability of product quality.

[0003] Currently, the preheating devices widely used in the industry generally adopt a structural design with battery storage furnaces set up before and after the battery preheating furnace. The specific workflow is as follows: First, the batteries are stored in the battery storage furnace located before the battery preheating furnace. Then, when the batteries need preheating, they are transferred to the battery preheating furnace. After the batteries complete the preheating process in the battery preheating furnace, they are transferred one by one in a certain order to the battery storage furnace located after the battery preheating furnace for temporary storage. Subsequently, a robotic arm removes the batteries one by one from the battery storage furnace for the next stage of production.

[0004] The aforementioned structure achieves battery preheating and storage functions to a certain extent. However, during the transfer of batteries from the preheating furnace to the storage furnace, the existing structural design and transmission methods result in slow transfer speeds. This issue leads to longer battery production cycles, reduced overall production efficiency, and an inability to match the ever-increasing demand for battery production scale, significantly hindering the improvement of battery production capacity. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a battery preheating device that can effectively shorten the battery production cycle and improve battery production efficiency to match the growing demand for battery production scale, thereby increasing battery production capacity.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A battery preheating device, comprising:

[0008] A battery storage furnace is used to store batteries. The battery storage furnace has multiple layers of first support plates arranged vertically inside, and a battery tray is placed on each layer of first support plates. The battery storage furnace also has a storage furnace inlet and outlet for the battery tray to enter and exit.

[0009] A battery preheating furnace is used to heat the battery. The battery preheating furnace is arranged side by side with the battery storage furnace. The battery preheating furnace has a preheating furnace inlet for the battery tray to enter and a preheating furnace outlet for the battery tray to exit.

[0010] A battery tray placement platform is provided for placing the battery tray, and the battery tray placement platform is located near the battery preheating furnace;

[0011] A battery tray transfer mechanism is used to transfer the battery tray in the battery preheating furnace to the battery tray placement platform.

[0012] As can be seen from the above technical solutions, in the battery production and processing process, the battery must first be placed on a battery tray, and then the battery tray together with the battery is placed in a battery storage furnace for storage. When the battery needs to be preheated, the battery tray placed in the battery storage furnace can be taken out from the inlet and outlet of the storage furnace by manual labor or robotic arms, and placed in the battery preheating furnace through the preheating furnace inlet. After the battery is preheated, the entire battery tray can be taken out from the battery preheating furnace outlet and placed on the battery tray placement platform by the battery tray transfer mechanism to wait for the next process.

[0013] Compared with the prior art, the battery preheating device disclosed in this utility model embodiment has the following technical advantages:

[0014] 1) Eliminating the need for a battery storage furnace not only saves floor space but also reduces processing and manufacturing costs;

[0015] 2) The battery tray transfer mechanism can transfer the battery trays together with the batteries in the battery preheating furnace to the battery tray placement platform. The batteries do not need to be transferred one by one into the battery storage furnace in a certain order. Therefore, it greatly shortens the battery production cycle and improves work efficiency, thereby meeting the growing demand for battery production scale and greatly improving battery production capacity.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Please refer to... Figures 1 to 6 .

[0035] Please refer to Figures 1 to 3 The battery preheating device disclosed in this embodiment includes a battery storage furnace 100, a battery preheating furnace 200, a battery tray placement platform 300, and a battery tray transfer mechanism. The battery storage furnace 100 stores batteries 900.

The battery storage furnace 100 also has a storage furnace inlet / outlet 102 for the battery trays 800 to enter and exit. Battery preheating furnace 200 is used to heat batteries. Battery preheating furnace 200 and battery storage furnace 100 are arranged side by side. Battery preheating furnace 200 has a preheating furnace inlet for battery tray 800 to enter and a preheating furnace outlet for battery tray 800 to exit. Battery tray placement platform 300 is used to place battery tray 800. Battery tray placement platform 300 is arranged close to battery preheating furnace 200. Battery tray transfer mechanism is used to transfer battery tray 800 in battery preheating furnace 200 to battery tray placement platform 300.

[0036] During the battery production and processing, the battery 900 is first placed on the battery tray 800, and then the battery tray 800 together with the battery 900 is placed in the battery storage furnace 100 for storage. When the battery needs to be preheated, the battery tray 800 placed in the battery storage furnace 100 can be taken out from the inlet / outlet 102 of the storage furnace by manual labor or robotic arms, and placed in the battery preheating furnace 200 through the preheating furnace inlet. After the battery is preheated, the entire battery tray 800 can be taken out from the battery preheating furnace outlet through the battery tray transfer mechanism and placed on the battery tray placement platform 300 to wait for the next process.

[0037] Compared with the prior art, the battery preheating device disclosed in this utility model embodiment has the following technical advantages:

[0038] 1) Eliminating one battery storage furnace 100 not only saves floor space but also reduces processing and manufacturing costs;

[0039] 2) The battery tray transfer mechanism can transfer the battery tray 800 and the battery 900 together in the battery preheating furnace 200 to the battery tray placement platform 300. The batteries do not need to be transferred one by one into the battery storage furnace 100 in a certain order. Therefore, it greatly shortens the battery production cycle and improves work efficiency, so as to match the growing demand for battery production scale and greatly improve the battery production capacity.

[0040] It should be noted that, please refer to Figure 3The battery storage furnace 100 includes three first side plates, a first top plate and a first bottom plate, wherein the three first side plates, the first top plate and the first bottom plate form a first battery storage chamber with one opening. Each first side plate is provided with multiple layers of first support plates 101, and each layer of first support plates 101 is flush, so as to achieve stable support for the battery tray 800.

[0041] As a further embodiment, the battery preheating device disclosed in this utility model embodiment also includes a lifting mechanism 700, which is disposed on the battery preheating furnace 200. The lifting mechanism 700 includes a driving component, a rotating component, and a lifting component. The driving component can drive the lifting component to perform lifting and lowering movements through the rotating component.

[0042] The lifting assembly is provided with a second support plate 201 along the vertical direction to support the battery tray 800. The second support plate 201 can support the battery tray 800 transferred out of the battery storage furnace 100.

[0043] As a specific embodiment, the lifting mechanism 700 disclosed in this utility model embodiment is preferably provided in two sets, and is arranged opposite to each other on both sides of the battery preheating furnace 200.

[0044] It should be noted that, please refer to Figure 4 The battery preheating furnace 200 includes two second side plates, a second top plate, and a second bottom plate. The two second side plates, the second top plate, and the second bottom plate form a second battery storage chamber with openings on both sides. Each second side plate is provided with multiple layers of third support plates 202. Each layer of third support plates 202 is flush with each other and corresponds to each layer of second support plates 201 to improve the stable support for the battery tray 800.

[0045] It should be further explained that the battery tray 800 placed in the battery storage furnace 100 needs to be placed in the first preset position in the battery preheating furnace 200 manually or by a robotic arm. Then, the lifting mechanism 700 raises or lowers the battery tray 800 to the second preset position in the battery preheating furnace 200, and then the battery tray 800 is transferred by the battery tray transfer mechanism. This setup eliminates the need to constantly adjust the placement height manually or mechanically, thereby further improving transfer efficiency.

[0046] The present invention does not limit the specific structure of the drive assembly, the rotation assembly, and the lifting assembly. Any structure that meets the requirements of the present invention is within the protection scope of the present invention.

[0047] As a further embodiment, the drive component disclosed in this utility model embodiment may be only a motor, or it may be a combination of a motor and a reducer, as long as it can achieve the drive function.

[0048] Of course, in order to achieve smooth operation of the lifting component, the drive component disclosed in this embodiment of the utility model includes a motor and a reducer, wherein the input end of the reducer is connected to the output end of the motor.

[0049] As a further embodiment, the rotating assembly disclosed in this utility model embodiment includes a first rotating assembly and a second rotating assembly. The first rotating assembly is disposed on the top of the battery preheating furnace 200 and connected to the output end of the reducer, and the second rotating assembly is disposed on the bottom of the battery preheating furnace 200.

[0050] As a further embodiment, the lifting assembly disclosed in this utility model embodiment includes at least a conveying component, with both ends of the conveying component respectively sleeved on the first rotating component and the second rotating component.

[0051] When the motor 701 is started, the power of the motor 701 is input to the input of the reducer 702 through the output end of the motor. The reducer 702 converts the high-speed rotational motion of the motor 701 into a smooth low-speed motion, and then outputs it to the rotating component through the output end of the reducer 702. The rotating component drives the lifting component to move up and down in the vertical direction.

[0052] Please refer to Figure 5 As a specific embodiment, the first rotating component disclosed in this utility model embodiment includes a first rotating shaft 703 and a first supporting bearing 704. The first rotating shaft 703 is connected to the output end of the reducer 702, and the first rotating shaft 703 and the first supporting bearing 704 are rotatably connected.

[0053] Among them, the first support bearing 704 is fixed on the top of the battery preheating furnace 200. There are two first support bearings 704, which are rotatably connected to both ends of the first rotating shaft 703 respectively. The output end of the reducer is connected to the middle part of the first rotating shaft 703.

[0054] The present invention does not limit the specific structure of the conveying component. The conveying component may be a conveyor belt, a conveyor chain, or other structures. Any structure that meets the requirements of the present invention is within the protection scope of the present invention.

[0055] When the conveyor is a conveyor belt or a conveyor chain, multiple second support plates 201 are sequentially arranged on the conveyor belt or conveyor chain in a vertical direction.

[0056] Its specific working principle is as follows: the motor 701 transmits power to the reducer 702, the reducer 702 transmits power to the first rotating shaft 703, the first rotating shaft 703 rotates under the support of the first support bearing 704. Since the first rotating shaft 703 and the second rotating shaft are connected by a conveyor belt or a conveyor chain, the second rotating shaft 708 will also rotate under the action of the conveyor belt or conveyor chain, so as to realize the conveyor belt or transmission chain moving up and down in the vertical direction.

[0057] As a further embodiment, the first rotating component disclosed in this utility model embodiment further includes a first support sleeve, the first support sleeve is fixed on the first rotating shaft 703, and one end of the transmission component is sleeved on the first support sleeve.

[0058] The second rotating assembly also includes a second support sleeve, which is disposed on the second rotating shaft, and the other end of the conveying component is sleeved on the second support sleeve.

[0059] The first and second support sleeves not only enhance the stability of the overall structure and effectively disperse the complex loads borne by the first and second rotating shafts during operation, preventing them from affecting the battery transfer accuracy due to deformation under force, and significantly reducing frictional losses between the first and second rotating shafts and other components, but also play an auxiliary positioning role.

[0060] This embodiment of the utility model does not limit the specific structure of the battery tray placement platform 300. Any structure that meets the usage requirements of this utility model is within the protection scope of this utility model.

[0061] The battery tray placement platform 300 disclosed in this embodiment of the utility model can simply be a support platform used to support the battery tray 800.

[0063] The placement plate 302 is mounted on the support frame 301 to support the battery tray 800. The heating element is mounted on the placement plate 302, which enables efficient preheating of the battery. The flat surface of the placement plate 302 ensures that the battery tray 800 is subjected to uniform force when placed, preventing deformation of the battery tray 800 and protecting the battery 900 from external damage. This ensures that the battery 900 reaches the required temperature during the preheating process, avoiding local overheating or insufficient temperature, and ensuring the consistency and stability of the preheating effect of the battery 900. This provides a reliable guarantee for the smooth implementation of subsequent processing technology and also improves the production quality of the battery 900.

[0064] This utility model embodiment does not limit the specific structure of the battery tray transfer mechanism. The battery tray transfer mechanism can be a robotic arm or a conveyor belt. Any structure that meets the usage requirements of this utility model is within the protection scope of this utility model.

[0065] When the battery tray transfer mechanism is a robotic arm, the robotic arm can be placed on one side close to the battery preheating furnace 200 and the battery tray placement platform 300. The robotic arm directly grabs the battery tray 800 placed in the battery preheating furnace 200 and places it on the battery tray 800 placement platform.

[0066] When the battery tray transfer mechanism is a conveyor belt, a corresponding conveying mechanism is required to transport the battery tray 800 placed in the battery preheating furnace 200 to the battery tray placement platform 300.

[0068] Specifically, the detection component detects whether the batteries placed on the battery tray placement platform 300 are qualified and transmits the detection results to the controller. After the controller identifies qualified and unqualified batteries, it controls the gripping component to grip the qualified batteries and place them on the qualified battery conveying mechanism 500 to be transported to the preset position, while the unqualified batteries are placed on the qualified battery placement rack 600 to wait for the next process.
