Description

【Technical Field】 【0001】 The present invention relates to a conveying system for electrode materials, and more particularly, to a conveying system for powdery electrode materials. Specifically, the present invention relates to a conveying system for electrode materials that can prevent clogging of the inlet by electrode materials by applying air pressure and vibration to the inlet of the stirring unit. 【0002】 This application claims the benefit of priority based on Korean Patent Application No. 10-2023-0071697, filed on June 2, 2023, and all the contents disclosed in the document of the Korean patent application are incorporated herein by reference. 【Background Art】 【0003】 A secondary battery is a rechargeable battery, and is configured to repeatedly charge and discharge by ions in an electrolyte moving between a positive electrode and a negative electrode insulated by a separator. The secondary battery may include an electrode assembly and a case containing the electrode assembly, and the electrode assembly is formed by alternately laminating a positive electrode, a negative electrode, and a separator. 【0004】 The secondary battery manufacturing process includes an electrode process, an assembly process, and an activation process. Here, the electrode process is a process of manufacturing a positive electrode and a negative electrode. The positive electrode or the negative electrode is manufactured through the following processes in sequence. 【0005】 The electrode process includes a mixing process, a coating process, a rolling process, a slitting process, and a notching process. 【0006】 FIG. 1 is a schematic view showing a conventional mixing device, and FIG. 2 is a schematic cross-sectional view taken along line A-A of FIG. 1. 【0007】 The mixing process is a process of weighing and mixing various electrode materials, and in the mixing process, the various electrode materials are mixed to form a liquid slurry. 【0008】 A slurry is a mixture of an active material, a conductive material, a binder, and a solvent. The active material and conductive material are dry-mixed in powder form. Then, the active material and conductive material are wet-mixed with a solvent containing the binder to form a slurry. 【0009】 The mixing device 10 includes a material supply hopper 20 into which powdered electrode material 50 is introduced, and a stirring section 30 into which the electrode material 50 supplied from the hopper 20 is stirred. 【0010】 Various active materials can be used as the powdered electrode material 50, depending on the type of secondary battery product. In particular, the positive electrode active material and negative electrode active material are used in very large quantities and are mainly supplied to the mixing device 10 in powder form. 【0011】 Each electrode material 50 introduced into the stirring section 30 has a different transport time to the stirring section 30 depending on the characteristics of each material, and the mixing time for the raw materials to be mixed in the mixing device 10 also differs. 【0012】 Furthermore, due to the characteristics of the electrode material 50, during the process of transporting it from the material supply hopper 20 to the stirring section 30, a phenomenon occurs where the inlet 31 of the stirring section 30 and / or the piping section 40 connecting the material hopper 20 and the inlet 31 of the stirring section 30 become clogged due to the aggregation phenomenon among the electrode material 50. On the other hand, the inlet 31 of the stirring section 30 and the piping section 40 can be connected via a clamp 60. 【0013】 Here, the aggregation phenomenon among the powdered electrode materials 50 is caused by the properties of the electrode materials 50, and as an example, the aggregation phenomenon of the powder may be caused by a chemical reaction between the internal moisture components of the mixing device 10 and the powdered electrode materials 50. 【0014】 If the inlet 31 and / or piping section 40 of the stirring section 30 become clogged, the transport time required for the electrode material 50 to be transported to the stirring section 30 will increase. Also, if the inlet 31 of the stirring section 30 becomes clogged and the input area of ​​the inlet 31 becomes smaller, it becomes difficult to accurately calculate the input area that the electrode material 50 passes through the inlet 31 per unit time. 【0015】 This could lead to problems such as being unable to input the electrode material 50 in a fixed quantity, and when the inlet 31 of the stirring section 30 becomes clogged, a problem arises in that a defective slurry is produced due to a measurement error of the electrode material 50. 【0016】 Conventionally, when the inlet 31 of the piping section 40 and / or the stirring section 30 became clogged during the mixing process, the operator had to separate the clamp 60 and the piping section 40 and manually crush the electrode material 50 (e.g., positive electrode active material, negative electrode active material, etc.) that had solidified into a lump at the inlet 31 of the piping section 40 and / or the stirring section 30. This resulted in the mixing process not being performed during the working time, leading to a decrease in slurry productivity. [Overview of the Initiative] [Problems that the invention aims to solve] 【0017】 The present invention aims to provide an electrode material transport system that can prevent clogging of the inlet of the stirring section by electrode material during the mixing process by applying air pressure and vibration to the inlet of the stirring section. 【0018】 Furthermore, the present invention aims to provide an electrode material transport system that can prevent clogging at the inlet of the stirring section and shorten the transport time of the electrode material. [Means for solving the problem] 【0019】 To solve the aforementioned problems, an electrode material transport system according to one embodiment of the present invention includes: an agitation section having an inlet into which electrode material is introduced and configured to perform a mixing process on the electrode material; a sensor section configured to measure the pressure inside the agitation section; an air injection section located at the inlet of the agitation section and configured to inject air into the inlet; a vibration section configured to apply vibration to the inlet; and a control section configured to adjust the air injection pressure of the air injection section based on the pressure inside the agitation section. In one example, the electrode material may be a powder electrode material. 【0020】 The air injection unit may include a plurality of air nozzles arranged in the inlet portion so as to inject air along the injection direction of the electrode material, a pneumatic pressure supply unit that provides pneumatic pressure to each air nozzle, and a regulator for adjusting the pneumatic pressure supplied to each air nozzle. In one example, the pneumatic pressure supply unit may include an air pump, and the regulator can adjust the pressure (pneumatic pressure) of the air injected from the air nozzle by adjusting the flow rate of the air. 【0021】 Also, the plurality of air nozzles may be arranged apart along the circumferential direction of the inlet portion of the stirring unit. 【0022】 Also, the vibration unit may include an air turbine vibrator. 【0023】 Also, the control unit may be provided to operate the air injection unit and the vibration unit in the input mode in which the electrode material is input into the stirring unit. 【0024】 Also, in the input mode, the control unit can operate the air injection unit so that air is injected at a first operating pressure lower than the internal pressure of the stirring unit. 【0025】 Also, in the input mode, the first operating pressure may be 0.1 MPa to 0.6 MPa. 【0026】 Also, in the input mode, the control unit can control the operation of the vibration unit so that vibration is applied at an intensity of 1 kgf to 60 kgf. 【0027】 Also, the electrode material conveying system may include a material supply unit having an outlet portion for supplying the electrode material to the stirring unit, and a piping unit that connects the outlet portion and the inlet portion and guides the conveyance of the electrode material from the material supply unit to the stirring unit. 【0028】 Also, the piping unit may include a first pipe connected to the stirring unit, a second pipe connected to the material supply unit, and a vibration reduction tube provided in the second pipe. 【0029】 Also, the first pipe and the second pipe can be connected via a clamp. The first pipe can constitute the inlet part of the stirring unit, and the second pipe can constitute the outlet part of the material supply unit. 【0030】 Also, the air injection part and the vibration part can be provided on the first pipe respectively. In one example, the air injection part can be provided to inject air inside the first pipe, and the vibration part can be provided to apply vibration to the first pipe. 【0031】 Also, the electrode material conveying system is mounted on the second pipe and can include an air knocker provided to strike the second pipe during the electrode material input mode. 【0032】 Also, the control unit can be provided to continuously operate the air injection part and the vibration part and operate the air knocker at a predetermined time interval during the input mode. 【0033】 Also, the vibration reduction tube can be formed of a silicon material. Also, the vibration reduction tube can be provided to surround a partial area of the second pipe. 【0034】 Also, the electrode material conveying system can include a vent pipe connected to the stirring unit. The control unit can be provided to open the vent pipe to the outside during the input mode. When the air pressure injected from the air injection part is applied inside the stirring unit during the input mode, the pressure inside the stirring unit can be increased. At this time, by opening the vent pipe to the outside, the pressure inside the stirring unit can be maintained constant. An electromagnetic valve can be provided in the vent pipe. 【0035】 Also, the control unit can operate the air injection part so that air is injected at a second operating pressure greater than the first operating pressure when the pressure inside the stirring unit decreases during the input mode. 【Advantages of the Invention】 【0036】 As described above, the electrode material transport system according to one embodiment of the present invention has the following effects. 【0037】 By applying air pressure and vibration to the inlet of the stirring section, clogging of the inlet by electrode materials during the mixing process can be prevented. In particular, when the electrode material is being introduced, air can be injected into the inlet of the stirring section to prevent aggregation of powdered electrode materials. 【0038】 Furthermore, the air ejected from the air nozzle is sprayed in the direction in which the electrode material is introduced, pushing the powdered electrode material in that direction and allowing it to be introduced into the stirring section in powder form. 【0039】 Furthermore, during the electrode material input mode, applying vibration to the inlet of the stirring section can prevent the electrode material from adhering to the inner surface of the inlet. 【0040】 Furthermore, by preventing clogging of the inlet of the stirring section by the electrode material, the transport time of the electrode material can be shortened, thereby improving the productivity of the slurry. 【0041】 Furthermore, it is possible to minimize input area errors due to jamming of electrode material, and thus minimize measurement errors of electrode material.

The stirring section 130 is configured so that the stirring unit 133 operates when electrode material is introduced. When the stirring unit 133 operates, the drive unit causes the rotating shaft to rotate, and the plurality of blades attached to the rotating shaft rotate, mixing the electrode material 50 inside the stirring section 130. 【0052】 Furthermore, the electrode material transport system 100 may include an air injection unit 140 provided at the inlet 131 of the stirring unit 130, which is configured to inject air into the inlet 131. 【0053】 Furthermore, the electrode material transport system 100 may include a vibrating section 150 provided to apply vibration to the inlet section 131. 【0054】 Furthermore, the electrode material transport system 100 includes a control unit 190 that adjusts the air injection pressure of the air injection unit based on the pressure in the stirring unit 130. 【0055】 The sensor unit 135 may include one or more pressure sensors and is configured to measure the pressure inside the stirring unit 130. The measured pressure inside the stirring unit 130 is transmitted to the control unit 190, which is configured to adjust the pressure of the air injected through the air injection unit 140 based on the measured pressure inside the stirring unit 130. 【0056】 The air injection unit 140 is fluidly movable inside the inlet 131. The air injection unit 140 is configured to inject air from inside the inlet 131 at a predetermined air pressure. In this specification, the pressure of the air injected through the air injection unit 140 (air pressure) may be referred to as the operating pressure or injection pressure. 【0057】 Figure 6 is a diagram illustrating one operating state of an electrode material transport system 100 according to one embodiment of the present invention, and Figure 7 is an enlarged view of the inlet portion 131 shown in Figure 6. 【0058】 The air injection unit 140 may include a plurality of air nozzles 141 to 144 arranged within the inlet 131 to inject air along the feeding direction F1 of the electrode material 50. 【0059】 Furthermore, the air injection unit 140 may include an air pressure supply unit 149 connected to each air nozzle 141 to 144 and providing air pressure to each air nozzle 141 to 144, and a regulator 145 for adjusting the air pressure supplied to each air nozzle 141 to 144. In one example, the air pressure supply unit 149 may include an air pump, and the regulator 145 can adjust the pressure of the air injected from the air nozzles 141 to 144 by adjusting the airflow rate. 【0060】 Each air nozzle 141-144 may be provided at the inlet 131, spaced apart from the vibrating section 150. Alternatively, multiple air nozzles 141-144 may be arranged spaced apart along the circumferential direction of the inlet 131 of the stirring section 130. 【0061】 Referring to Figures 6 and 7, a plurality of air nozzles 141 to 144 may be provided within the inlet 131 such that the air injection direction A1 aligns with the electrode material input direction F1. 【0062】 The pneumatic supply unit 149 is connected to each air nozzle 141 to 144, and the pneumatic supply unit 149 provides air pressure to each air nozzle 141 to 144 when the electrode material 50 is being introduced. 【0063】 Furthermore, the electrode material transport system 100 may include a material supply unit 110 having an outlet 111 for supplying the electrode material 50 to the stirring unit 130, and the material supply unit 110 may include a hopper. The material supply unit 110 may also store powdered electrode material 50, and the electrode material 50 may be a positive electrode active material, a negative electrode active material, or a conductive material. 【0064】 Furthermore, the electrode material transport system 100 may include a piping section 170 that connects the outlet section 111 and the inlet section 131, and guides the transport of the electrode material 50 from the material supply section 110 to the stirring section 130. 【0065】 Furthermore, the piping section 170 may include a first pipe 175 connected to the stirring section 130, a second pipe 171 connected to the material supply section 110, and a vibration-reducing tube 173 provided on the second pipe 171. The first pipe 175 and the second pipe 171 may also be connected via a clamp 177. 【0066】 An outlet section 111 may be provided at the bottom of the material supply section 110, and the outlet section 111 is a passage through which the electrode material 50 is discharged from the material supply section 110. In addition, an inlet section 131 into which the electrode material 50 is introduced may be provided at the top of the stirring section 130. In this case, the first pipe 175 can constitute the inlet section 131 of the stirring section 130, and the second pipe 171 can constitute the outlet section 111 of the material supply section 110. 【0067】 In this structure, the electrode material 50 in the material supply unit 110 can be sequentially passed through the second pipe 171 and the first pipe 175 and fed into the stirring unit 130. 【0068】 Furthermore, the air injection unit 140 and the vibration unit 150 may each be provided in the first pipe 175. In one example, the air injection unit 140 may be provided to inject air inside the first pipe 175, and the vibration unit 150 may be provided to apply vibration to the first pipe 175. 【0069】 Furthermore, the control unit 190 may be configured to operate the air injection unit 140 and the vibration unit 150 when the electrode material 50 is introduced into the stirring unit 130. 【0070】 Furthermore, the control unit 190 can operate the air injection unit 140 so that air is injected at a first operating pressure lower than the internal pressure of the stirring unit 130 during the input mode. In one example, the first operating pressure during the input mode may be 0.1 MPa to 0.6 MPa. Alternatively, the first operating pressure may be 0.3 MPa to 0.4 MPa. 【0071】 During the electrode material 50 feeding mode, the air injection unit 140 functions to disperse the electrode material 50 into a powder by injecting air into the electrode material 50 flowing through the inlet 131, and to push the electrode material 50 in the electrode material feeding direction F1. 【0072】 Furthermore, the electrode material transport system 100 may include a vent pipe 210 connected to the stirring section 130. The control unit 190 may be configured to open the vent pipe 210 to the outside O when the electrode material 50 is being introduced. When the electrode material 50 is being introduced, the pressure inside the stirring section 130 can be increased by applying air pressure injected from the air injection section 140 into the stirring section 130. At this time, the pressure inside the stirring section 130 can be kept constant by opening the vent pipe 210 to the outside O. A solenoid valve 220 may be provided in the vent pipe 210. The solenoid valve 220 is configured to open and close the vent pipe 210. 【0073】 On the other hand, a filter may be provided in the vent pipe 210. Therefore, the fluid discharged from the agitation section 130 along the vent pipe 210 passes through the filter and is then discharged outside the conveying system 100. 【0074】 Referring to Figure 4, the vibrating section 150 may be located outside the inlet section 131. The vibrating section 150 may be configured to apply vibration to the first pipe 175, or it may be configured to apply vibration outside the first pipe 175. 【0075】 Furthermore, the vibrating unit 150 may be positioned at a distance from each of the air nozzles 141 to 144. 【0076】 Furthermore, the vibrating section 150 is provided to provide a vibration Fv of a predetermined magnitude to the inlet section 131. The intensity of the vibration Fv generated by the vibrating section 150 may be in the range of 1 kgf to 60 kgf. Alternatively, the intensity of the vibration Fv generated by the vibrating section 150 may be in the range of 20 kgf to 25 kgf. In other words, the control unit 190 can control the operation of the vibrating section 150 so that vibration is applied with an intensity of 1 kgf to 60 kgf when the electrode material 50 is being introduced. 【0077】 Furthermore, the vibrating section 150 may include an air turbine vibrator. An air turbine vibrator is a device that applies vibration to the inlet section 131 using compressed air as a power source. In one example, the air turbine vibrator is a known device and may be a vibrating machine that generates vibration force by rotating an internal rotary turbine gear. 【0078】 The vibrating unit 150 provides vibration Fv to the inlet 131 during the electrode material 50 input mode. When the vibrating unit 150 is activated, vibration occurs on the outside of the first pipe 175. In this way, by applying vibration Fv to the inlet 131 during the electrode material 50 input mode, it is possible to prevent the electrode material 50 from adhering to the inner surface of the inlet 131 (or the inner surface of the first pipe). 【0079】 As mentioned above, the piping section 170 connects the outlet section 111 of the material supply section 110 and the inlet section 131 of the stirring section 130, and the piping section 170 is responsible for guiding the electrode material 50 from the material supply section 110 to the stirring section 130. 【0080】 The second pipe 171 constitutes the outlet 111 of the material supply unit 110, and the second pipe 171 may be made of a rigid metal material. 【0081】 Furthermore, the first pipe 175 is detachably connected to the second pipe 171 by a clamp 177, and the first pipe 175 may be made of a rigid metal material. 【0082】 The electrode material transport system 100 may include an air knocker 180 mounted on the second pipe 171 and configured to strike the second pipe 171 when the electrode material 50 is being fed in. 【0083】 The air knocker 180 may be provided on the second pipe 171, and the air knocker 180 has the function of striking the second pipe 171 when the electrode material 50 is being introduced, thereby preventing the powdery electrode material 50 from adhering to the inner surface of the second pipe 171. 【0084】 The air knocker 180 is a known device and, in one example, may be a vibrating shocker that dislodges electrode material 50 adhering to the inner surface of the second pipe 171 by an indirect impact method using the reaction between compressed air and the magnetic force of a magnetic piston. 【0085】 When the air knocker 180 is activated, the force with which the air knocker 180 strikes the second pipe 171 causes vibration in the second pipe 171. If the vibration generated from the air knocker 180 is transmitted to the stirring unit 130 at this time, there is a possibility that the stirring unit 130 may malfunction. 【0086】 To prevent this, the vibration-reducing tube 173 may be provided so as to surround a portion of the second pipe 171. The vibration-reducing tube 173 may also be made of a silicon material. The vibration-reducing tube 173 can prevent vibrations from being transmitted from the second pipe 171 to the first pipe 175. 【0087】 The control unit 190 controls the operation of the material supply unit 110, the stirring unit 130, the air injection unit 140, the vibration unit 150, and the air knocker 180. 【0088】 When the electrode material 50 is being fed, the control unit 190 controls the operation of the material supply unit 110 so that the electrode material 50 is fed into the inlet 131 via the outlet 111 of the material supply unit 110. The control unit 190 also activates the stirring unit 130 when the electrode material 50 is being fed, opening the vent pipe 210 to the outside. 【0089】 In input mode, the electrode material 50 discharged from the material supply unit 110 is transported along the piping unit 170, passes through the inlet 131, and is fed into the stirring unit 130. 【0090】 Due to the characteristics of the electrode material 50, clogging may occur at the inlet 131. To resolve this, the control unit 190 controls the operation of the air injection unit 140 and the vibration unit 150 so that air pressure and vibration Fv are provided to the inlet 131 (first pipe) when the electrode material 50 is introduced into the stirring unit 130. 【0091】 The control unit 190 may be configured to operate the air injection unit 140 and the vibration unit 150 continuously and to operate the air knocker 180 at predetermined time intervals when the electrode material 50 is being introduced. In one example, when the electrode material 50 is being introduced, air is continuously injected into the first pipe 175 by the air injection unit 140, and vibration is continuously applied to the first pipe 175 by the vibration unit 150. 【0092】 Furthermore, the control unit 190 can control the operation of the vibration unit 150 so that a vibration Fv with an intensity of 1 kgf to 60 kgf is provided to the inlet 131 when the electrode material 50 is being introduced. 【0093】 In particular, the control unit 190 can control the operation of the air injection unit 140 so that air is supplied at a first operating pressure lower than the internal pressure of the stirring unit 130 when the electrode material 50 is being introduced. 【0094】 Furthermore, in the input mode, if the pressure inside the stirring section 130 decreases while air is being supplied at a first operating pressure lower than the internal pressure of the stirring section 130, the control unit 190 can operate the air injection section 140 so that air is injected at a second operating pressure higher than the first operating pressure. 【0095】 Specifically, during the electrode material 50 input mode, while the pressure in the stirring section 130 is maintained at a constant level (this pressure is called the "set pressure"), the air injection section 140 is activated to supply air at a first operating pressure. When the pressure in the stirring section 130 falls below the set pressure, the air injection section 140 can be activated to inject air at a second operating pressure greater than the first operating pressure. 【0096】 If electrode material 50 adheres to the inside of the first pipe 175, the air pressure supplied via the air injection unit 140 may not be properly transmitted to the stirring unit 130, and in this case, the pressure inside the stirring unit 130 may become low. At this time, the control unit 190 can resolve the clogging phenomenon by operating the air injection unit 140 so that air is injected at a second operating pressure greater than the first operating pressure. In addition, if the pressure in the stirring unit 130 falls below the set pressure, the control unit 190 can increase the vibration intensity of the vibration unit 150. 【0097】 On the other hand, if the pressure inside the stirring section 130 exceeds the set pressure, the control unit 190 can interrupt the injection mode and stop the operation of the air injection section 140 and the vibration section 150. 【0098】 The preferred embodiments of the present invention described above are disclosed for illustrative purposes only, and a person skilled in the art with ordinary skill in the invention will know that various modifications, alterations, and additions are possible within the spirit and scope of the invention, and such modifications, alterations, and additions should be considered to fall within the scope of the following claims. [Industrial applicability] 【0099】 According to one embodiment of the electrode material transport system, air pressure and vibration can be applied to the inlet of the stirring section to prevent clogging of the inlet by the electrode material during the mixing process.
