Description

Technical Field

[0001] The utility model relates to the technical field of battery production and processing equipment, in particular to a hydraulic pressure regulating self-heating restraint tray. Background Art

[0002] During the formation process of battery production, the heating method has a crucial impact on battery performance. Traditional formation processes mainly rely on methods such as environmental heating and bin heating, but these methods have some limitations and deficiencies.

[0003] Environmental heating usually means that the temperature of the entire production environment is increased, which leads to increased energy consumption and low heating efficiency because the heat is dispersed throughout the environment rather than concentrated on the battery. Although bin heating is relatively concentrated, it still cannot achieve precise temperature control for each battery, resulting in an impact on the consistency of battery formation.

[0004] In the design of traditional restraint trays, the upper plate of the tray is fixed. The heat generated by the battery during charge and discharge will cause expansion, which in turn affects the pressure on the battery. Due to the fixity of the tray, this expansion cannot be effectively alleviated, and the pressure on the battery may deviate from the designed value. This uneven distribution of pressure will lead to uneven charge and discharge of the battery, affecting its performance and lifespan.

[0005] More seriously, if the battery expands arbitrarily during the formation process, it may push adjacent batteries to shift. When this movement accumulates to the last battery, it may cause it to deviate too far from the predetermined position, making it impossible to accurately position the positive and negative electrodes of the battery, and may even lead to the failure of the operation in severe cases.

There are multiple groups of guide columns 2, and both ends are respectively fixedly arranged on both inner ends of the outer frame 1. There are several laminate assemblies 3, which are slidably arranged on multiple guide columns 2;

[0034] As Figure 1 and Figure 2 shown, the laminate assembly 3 includes a single-layer laminate 31, positioning guide columns 32 and a heating plate 34. There are two single-layer laminates 31, which are slidably connected through the positioning guide columns 32. There is an adjustment gap between the single-layer laminates 31. A pressure chamber 33 is arranged inside the single-layer laminate 31. The heating plate 34 is fixedly arranged in the pressure chamber 33 on the inner side of the single-layer laminate 31. The pressure chambers 33 of the two single-layer laminates 31 are nested and slidably arranged with each other, and a sealed cavity is formed inside. Laminate hanging plates 35 are fixedly arranged on both sides of the single-layer laminate 31, and the laminate hanging plates 35 are slidably arranged on the guide columns 2. The pressure chamber 33 is connected to an oil tank (not shown) through a pipeline, and a hydraulic overflow valve (not shown) is arranged on the oil tank (not shown). A pressure sensor is installed on the laminate assembly 3. The positioning guide columns 32 are located outside the inner side of the single-layer laminate 31 and are evenly distributed on the outside of the pressure chamber 33. A temperature sensor is arranged inside the outer frame 1.

[0035] As Figure 3 shown, the hydraulic pressure regulating self-heating restraint tray further includes a centering assembly 4. The centering assembly 4 is evenly arranged on the guide columns 2 and is located between the laminate assemblies 3. The centering assembly 4 includes a spring baffle 41 and a spring 42. The spring baffle 41 is fixedly arranged on the guide columns 2 and is evenly distributed between the laminate assemblies 3. The spring 42 is arranged outside the guide columns 2 and is evenly distributed between the spring baffle 41 and the laminate assemblies 3.

[0036] As Figure 4 shown, the hydraulic pressure regulating self-heating restraint tray further includes a heat dissipation assembly 5. The heat dissipation assembly 5 includes a fixing plate 51 and a heat dissipation fan 52. The fixing plate 51 is fixedly arranged at the lower part inside the outer frame 1 and is located below the laminate assembly 3. The heat dissipation fans 52 are evenly and fixedly installed on the fixing plate 51. The required electrical components and liquid path and pipeline components are all installed at the bottom inside the outer frame 1.

[0037] As Figures 1 to 4 shown

[0038] During the entire operation of the battery, the utility model can achieve self-heating, provide a constant restraint pressure, and maintain the position of the battery unchanged during the operation process. The hydraulic pressure-regulating self-heating restraint tray is divided into two working positions on the left and right. There are a total of 8 guide posts 2, with 8 guide posts 2 in a group. A layer plate hanging plate 35 is installed on the guide posts 2. The layer plate hanging plate 35 is mechanically connected to the single-layer plate 31. The layer plate hanging plate 35 is controlled by the input and output of the liquid in the pressure cavity 33 on the guide posts 2 to open and retract. Oil tanks (not shown) are provided at the head and tail ends of the outer frame 1. Compressed liquid is injected into the pressure cavity 33 of each layer plate assembly 3. The pressure cavity 33 overcomes the force of the spring 42 and opens in the opposite direction. The heating plate 34 inside the pressure cavity 33 will heat the battery. The heating plate 34 transfers heat or absorbs heat through the liquid in the pressure cavity 33 to keep the temperature of the outer layer plate consistent. The cooling fan 52 dissipates heat from the battery in real time during operation to maintain temperature stability.

[0039] The outer frame is the main body of the restraint tray, which bears all components and the battery 100 to realize material transfer and operation on the automatic production line; centering component: composed of several groups of springs 42 and spring baffles 41, the single-layer plate 31 can expand outward under the action of the pressure cavity 33 and remain stationary under the action of the spring 42. The battery 100 does not move during the operation process, that is, the distance between adjacent batteries 100 remains unchanged. The same distance between adjacent batteries can be achieved. The self-expansion and contraction of the battery 100 during the operation process will not affect the change of its own central position and the position of adjacent batteries 100, ensuring stable operation and realizing automatic mass production of the production line; the layer plate assembly 3 that can generate self-heat and pressure: is the device that generates the restraint force and temperature required for the operation of the battery 100. Different pressures can be achieved according to different types of batteries 100, and the pressure can be maintained stable throughout the process. At the same time, it can provide the ambient temperature required for the operation of the battery 100; the heat dissipation component 5: dissipates the excessive heat generated during the charging and discharging process of the battery 100 to maintain the stable ambient temperature of the battery 100 throughout the process.

[0040] An adjustment gap is provided between the single-layer plates 31 of the layer plate assembly 3. The relative positions between the single-layer plates can change. The positioning guide posts 32 can limit the opening amplitude between the single-layer plates 31. The pressure of the outer side of the single-layer plate 31 pressing on the battery 100 can be adjusted according to the pressure of the compressed liquid. The pipelines of each pressure cavity 33 are connected in the same source and kept consistent. At the same time, a hydraulic overflow valve is set on the oil tank. When the battery 100 expands and causes the pressure in the pipeline to rise, a part of the pressure set by the hydraulic overflow valve will overflow to the outside, so as to keep the restraint pressure of the battery 100 constant.

[0041] The cooling fan 52 adopts analog control of the fan speed. When the temperature sensor collects that the temperature of a certain channel of the laminate assembly 3 exceeds the preset value, the corresponding cooling fan 52 will adjust the speed to increase the air volume to achieve the purpose of accelerating the heat dissipation speed. When the temperature of the laminate assembly 3 drops to the set temperature, the wind speed of the cooling fan 52 decreases or remains constant. The air volume of each cooling fan 52 can be adjusted and controlled separately according to the temperature sensor.

[0042] The above describes the preferred embodiments of the present application in detail. However, the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present application.
