Description

Technical Field

[0001] The utility model relates to the technical field of battery production and processing equipment, in particular to an airbag 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 cause 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 locate the positive and negative electrodes of the battery, and may even lead to the failure of the operation in severe cases.

A plurality of laminate assemblies 3 are provided and are slidably arranged on the plurality of guide columns 2. 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 fixed on the guide column 2 and is evenly distributed between the laminate assemblies 3. The spring 42 is arranged outside the guide column 2 and is evenly distributed between the spring baffle 41 and the laminate assembly 3.

[0033] As Figure 3 shown, the laminate assembly 3 includes a single-layer laminate 31, positioning guide columns 32, an airbag 33, a heating plate 34 and a silicone sheet 35. Two single-layer laminates 31 are provided and are slidably connected through the positioning guide columns 32. An adjustment gap is provided between the single-layer laminates 31. The airbag 33 is sandwiched between the single-layer laminates 31. The heating plate 34 is fixedly arranged outside the single-layer laminate 31. The silicone sheet 35 is fixedly arranged outside the heating plate 34. Laminate hanging plates 36 are fixedly arranged on both sides of the single-layer laminate 31, and the laminate hanging plates 36 are slidably arranged on the guide columns 2. A pressure overflow valve (not shown) is provided on the air path of the airbag 33. A pressure sensor (not shown) is installed on the laminate assembly 3. A groove 37 is provided on the inner side of the single-layer laminate 31, the airbag 33 is arranged inside the groove 37, and the positioning guide columns 32 are located outside the inner side of the single-layer laminate 31 and are evenly distributed outside the airbag 33.

[0034] As Figure 4 shown, an airbag 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. A temperature sensor (not shown) is provided inside the outer frame 1. The required electrical components and air path and pipeline components are all installed at the bottom inside the outer frame 1.

[0035] As Figures 1 to 4 shown

[0036] During the whole operation period of the battery, the utility model can realize self-heating, provide a constant restraint pressure, and maintain the position of the battery unchanged during the operation process. The tray is divided into two working positions on the left and right. There are a total of 8 guide posts 2, and every 8 guide posts 2 form a group. A shelf hanging plate 36 is installed on the guide posts 2. The shelf hanging plate 36 is mechanically connected to the single-layer shelf 31. On the guide posts 2, the expansion and retraction of the airbag 33 are carried out. An air box (not shown) is provided at each end of the head and tail of the outer frame 1. Compressed gas is injected into the airbag 33 inside each shelf assembly 3. The airbag 33 overcomes the force of the spring 42 and expands in the opposite direction. The heating plate 34 on the outside of the single-layer shelf will heat the battery, and the cooling fan 52 dissipates heat from the battery in real time during the operation to maintain the temperature stability.

[0037] The outer frame is the main body of the restraint tray, which bears all components and the battery 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 shelf 31 can expand outward under the action of the airbag 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 realized. The self-expansion and contraction of the battery 100 during the operation process will not affect the change of its own center position and the position of adjacent batteries 100, ensuring stable operation and realizing automatic mass production of the production line; the shelf 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 realized 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 environmental temperature required for the operation of the battery 100; the heat dissipation component 5: is to dissipate the excessive heat generated during the charging and discharging process of the battery 100 to maintain the stable environmental temperature of the battery 100 throughout the process.

[0038] An adjustment gap is provided between the single-layer shelves 31 of the shelf assembly 3. The relative positions between the single-layer shelves can change. The positioning guide posts 32 can limit the opening amplitude between the single-layer shelves 31. The pressure on the outside of the single-layer shelf 31 pressing the battery 100 can be adjusted according to the pressure of the compressed air. The air paths of each airbag 33 are connected in the same source and kept consistent. At the same time, a pressure overflow valve is set on the air path. When the pressure in the air path rises due to the expansion of the battery, a part of the pressure set by the pressure overflow valve overflows to the outside, so as to keep the restraint pressure of the battery 100 constant.

[0039] The cooling fan 52 uses analog control for the fan speed. When the temperature acquired by 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 individually according to the temperature sensor.

[0040] 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.
