Description

Technical Field

[0001] The utility model relates to auxiliary facilities for battery production, in particular to a device for storing and transporting magnetic bar components. Background Art

[0002] Battery pole pieces are the core of the battery's electrochemical reaction, mainly including positive and negative pole pieces, which each play the role of oxidation and reduction reactions in the battery. The production of battery pole pieces includes the following structural stages:

[0003] Slurry preparation: the active material (such as lithium cobalt oxide or graphite), conductive agent (such as acetylene black), binder (such as polyvinylidene fluoride PVDF) and solvent (such as N-methylpyrrolidone NMP) are mixed evenly to prepare a uniform slurry; slurry coating: the prepared slurry is evenly coated on the current collector (usually aluminum foil or copper foil); pole piece rolling; pole piece cutting; pole piece drying.

[0004] During the preparation of slurry, metal impurities are easily mixed in the slurry. If the metal impurities adhere to the coating area of ​​the pole piece during the subsequent coating process, it will have an adverse effect on the quality of the battery, including: causing the battery capacity to decrease; increasing the internal resistance of the battery, affecting the discharge efficiency and energy output of the battery; piercing the diaphragm to cause an internal short circuit, accelerating the decline of battery performance, reducing the cycle life, etc., and even causing the battery to catch fire or explode.

[0005] In order to avoid the above adverse effects, a magnetic rod assembly will be used to absorb the mixed metal impurities in the slurry before the pole piece coating. The existing magnetic rod assembly includes a magnetic rod body, a magnetic rod guard and a magnetic rod handle. The two sides of the magnetic rod guard are respectively connected to the magnetic rod body and the magnetic rod handle. And the magnetic rod guard protrudes from the magnetic rod body and the magnetic rod handle. After the magnetic rod assembly is finished absorbing impurities, it will be cleaned and then transported and stored. Most of the existing technologies use a storage and transportation integrated device to reduce the steps of moving the magnetic rod assembly from the storage place to the transportation device, which is conducive to improving production efficiency.

[0006] However, when the magnetic bar assembly is placed on a storage and transportation device after cleaning, the moisture attached to the surface of the magnetic bar body is not easy to dry naturally, which can easily cause the magnetic bar body to rust. In addition, the magnetic bar assemblies are prone to collide with each other during transportation, causing damage to the magnetic bar assembly. Utility Model Content

[0046] like Figure 1-Figure 3 As shown, a device for storing and transporting magnetic bar assemblies comprises: a placement bin, the placement bin comprises a plurality of workstations, and one of the workstations is used to place a magnetic bar assembly; a bellows 8, the cavity of the bellows 8 is connected to the cavity of the placement bin; and a walking device, the walking device is arranged at the bottom of the placement bin.

[0047] One station corresponds to one magnetic bar assembly. When the magnetic bar assembly is set in the placement bin, two adjacent magnetic bar assemblies will not come into contact, so as to avoid the metal impurities left on the surface of the magnetic bar body 10 from damaging the adjacent magnetic bar assemblies and affecting the quality of the magnetic bar assembly. The cavity of the bellows 8 is connected to the cavity of the placement bin, so that the gas of the bellows 8 can generate airflow, accelerate the evaporation of water on the surface of the magnetic bar body 10, and avoid rusting of the magnetic bar body 10 as much as possible. The walking device is set at the bottom of the placement bin to facilitate the transportation of the magnetic bar assembly.

[0048] like Figure 1-Figure 4 As shown, in this embodiment, the workstation includes a limit tube 2, a top plate 4, a bottom plate 7 and a connecting rod 6, and the limit tube 2 is arranged vertically. When the limit tube 2 is arranged vertically, when the magnetic bar body 10 is placed inside the limit tube 2, the water on the surface of the magnetic bar body 10 and the remaining metal impurities can fall due to gravity. And the form of setting the limit tube 2 is to avoid contact between two adjacent magnetic bar assemblies as much as possible, and to avoid damage to the magnetic bar assembly as much as possible. The top plate 4 is arranged at the opening corresponding to the limit tube 2, and the limit tube 2 is arranged below the opening. The bottom plate 7 is also provided with an opening corresponding to the limit tube 2. The bottom plate 7 is connected to the bellows 8. In this embodiment, a total of eight limit tubes 2 are arranged in this device, and different numbers of limit tubes 2 can be arranged according to needs in actual use. The top plate 4 and the bottom plate 7 are both rectangular plates, and the sizes of the top plate 4 and the bottom plate 7 correspond. The top plate 4 and the bottom plate 7 are connected by four connecting rods 6. The four connecting rods 6 are respectively arranged at the four corners of the rectangle. The limiting tube 2 used in this embodiment is in the form of a round tube, and can also be changed to a square tube or other special-shaped tubes as needed.

[0049] like Figure 5-Figure 6 As shown, the bottom of the limiting tube 2 is detachably provided with a first filter 14. The bottom of the limiting tube 2 is provided with a first filter 14, which can catch the metal impurities left on the surface of the magnetic rod body 10. The first filter 14 is detachable, and the first filter 14 can be removed to pour out the metal impurities, so as to avoid the accumulation of metal impurities and wind blocking, which affects the drying of the magnetic rod.

[0050] like Figure 1-Figure 4As shown, the top of the limit tube 2 is connected to the outside world, and the bellows 8 is detachably arranged below the top plate 4, and the bellows 8 can generate negative pressure. The bellows 8 is connected to an external air source through a quick pipe joint 3, and the side plate of the bellows 8 opposite to the quick pipe joint 3 is provided with an air outlet, and the gas can generate convection along the bellows 8. According to the Bernoulli principle, it can be known that the bellows will generate negative pressure. In actual use, the size of the negative pressure can be changed by adjusting the wind speed of the external air source according to different needs.

The bellows 8 is arranged at the bottom of the placement bin to generate negative pressure, and the gas can enter the limiting tube 2 through the top of the limiting tube 2, so the gas can move from top to bottom along the limiting tube 2, which can not only accelerate the evaporation of water on the surface of the magnetic rod body 10, but also facilitate the shedding of metal impurities left on the surface of the magnetic rod body 10. The bellows 8 is detachably arranged below the bottom plate 7 to facilitate the disassembly of the first filter 14. In actual use, the bellows 8 can also be connected to an external suction device so that the bellows 8 generates negative pressure. When the bellows 8 is connected to an external suction device, the bellows 8 can not only be arranged below the limiting tube 2, but also on the side of the limiting tube 2. As long as the suction port of the bellows 8 is connected to the bottom of the limiting tube 2, it will be fine.

A second filter 15 is detachably arranged between two adjacent blocks 13. When external air enters the limit tube 2 through the second filter 15 from the gap between the two adjacent blocks, impurities in the external air can be prevented from entering the limit tube 2 as much as possible, thereby preventing impurities from being adsorbed on the surface of the magnetic bar body 10 and affecting the quality of the magnetic bar assembly.

[0052] The walking device also includes a handrail 1 connected to one side of the top plate 4 to facilitate the operation of the staff. The walking device includes a universal wheel 9. In this embodiment, there are four universal wheels 9, which are arranged at the bottom end of the connecting rod 6.

The structure of the limiting tube 2 can also be changed, and the limiting tube 2 can be arranged into two parts: a fixed part and an opening and closing part. The fixed part and the opening and closing part are connected by a hinge, so the opening and closing part can rotate along the fixed part. The connecting line between the fixed part and the opening and closing part is parallel to the axis of the limiting tube 2 and passes through the limiting tube 2. The opening and closing part opens and closes, the magnetic bar assembly is placed in, and then the opening and closing part is closed. Preferably, the connecting line between the opening and closing part and the fixed part can be provided with rubber to improve the airtightness of the limiting tube 2, which is beneficial to improving the evaporation rate of water on the surface of the magnetic bar body 10.

[0056] The temperature of the wind blown by the bellows 8 is greater than or equal to 40° C. and less than or equal to 75° C. In this embodiment, the wind blown by the bellows directly blows the magnetic bar assembly, and the temperature is within the above range, which is conducive to increasing the evaporation rate of the water on the surface of the magnetic bar body 10 .
