Description

[Technical Field]

[0001] The present invention relates to a conveying system for electrode material, in particular to a conveying system for powdered electrode material, and more specifically to a conveying system for electrode material that can prevent clogging of the inlet with electrode material by applying air pressure and vibration to the inlet of the agitator.

[0002] This application claims the benefit of priority based on Korean Patent Application No. 10-2023-0071697, filed on June 2, 2023, and all contents disclosed in the documents of this Korean patent application are incorporated herein by reference. [Background technology]

[0003] A secondary battery is a rechargeable battery that is configured to repeatedly charge and discharge by the movement of ions in an electrolyte between a positive electrode and a negative electrode that are insulated by a separator. The secondary battery may include an electrode assembly and a case that houses the electrode assembly, and the electrode assembly is formed by alternately stacking positive electrodes, negative electrodes, and separators.

[0004] The secondary battery manufacturing process includes an electrode process, an assembly process, and an activation process. Here, the electrode process is a process for manufacturing a positive electrode and a negative electrode. The positive electrode or negative electrode is manufactured through the following processes in order.

[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 diagram showing a schematic view of a conventional mixing device, and FIG. 2 is a schematic cross-sectional view taken along line AA in FIG.

[0007] The mixing step is a step of measuring and mixing various electrode materials, and the various electrode materials are mixed in the mixing step to form a liquid slurry.

[0008] The slurry is a mixture of an active material, a conductive material, a binder, and a solvent. The active material and the conductive material are dry-mixed in powder form. The active material and the conductive material are then wet-mixed in a solvent that has dissolved the binder to form a slurry.

[0009] The mixer 10 includes a material supply hopper 20 into which the powdered electrode material 50 is introduced, and a stirring section 30 in which the electrode material 50 supplied from the hopper 20 is stirred.

[0010] Various active materials can be used depending on the type of secondary battery product as the powdered electrode material 50. In particular, the positive electrode active material and the negative electrode active material are used in very large amounts, and are supplied to the mixer 10 mainly in powder form.

[0011] The electrode materials 50 fed into the stirring section 30 have different transport times for feeding into the stirring section 30 depending on the properties of the materials, and the mixing times for mixing the raw materials in the mixer 10 also differ.

[0012] Furthermore, due to the characteristics of the electrode material 50, during the process of being transported from the material supply hopper 20 to the agitator 30, a phenomenon occurs in which the electrode material 50 aggregates, causing clogging of the inlet 31 of the agitator 30 and / or the piping 40 connecting the material hopper 20 and the inlet 31 of the agitator 30. Meanwhile, the inlet 31 of the agitator 30 and the piping 40 can be connected via a clamp 60.

[0013] Here, the agglomeration phenomenon between the powdered electrode material 50 is caused by the characteristics of the electrode material 50, and as an example, the agglomeration phenomenon of the powder may be caused by a chemical reaction between the internal moisture component of the mixing device 10 and the powdered electrode material 50.

[0014] If the inlet 31 of the stirring section 30 and / or the piping section 40 are clogged, it will take a longer time to transport the electrode material 50 to the stirring section 30. Furthermore, if the inlet 31 of the stirring section 30 is clogged and the input area of ​​the inlet 31 becomes narrow, it will be difficult to accurately calculate the input area through which the electrode material 50 passes through the inlet 31 per unit time.

[0015] This may result in the problem of not being able to add the electrode material 50 in a fixed amount, and when the inlet 31 of the stirring section 30 becomes clogged, there is a problem that a defective slurry is produced due to a measurement error in the electrode material 50.

[0016] Conventionally, when the piping section 40 and / or the inlet section 31 of the agitation section 30 become clogged during the mixing step, an operator must 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 has solidified into clumps in the piping section 40 and / or the inlet section 31 of the agitation section 30. This causes the mixing step to be suspended during the working time, resulting in a problem of reduced productivity of the slurry. Summary of the Invention [Problem to be solved by the invention]

[0017] An object of the present invention is to provide a conveying system for electrode material that can apply air pressure and vibration to the inlet of the agitator to prevent the inlet from being clogged with electrode material during the mixing process.

[0018] Another object of the present invention is to provide a transport system for electrode material that can prevent clogging of the inlet of the stirring section and shorten the transport time of the electrode material. [Means for solving the problem]

[0019] In order to solve the above-mentioned problems, an electrode material conveying system according to one embodiment of the present invention includes: a stirring unit having an inlet through which the electrode material is introduced and configured to perform a mixing process on the electrode material; a sensor unit configured to measure the pressure within the stirring unit; an air injection unit configured to inject air into the inlet at the inlet of the stirring unit; a vibration unit configured to apply vibration to the inlet; and a control unit configured to adjust the injection pressure of the air from the air injection unit based on the pressure within the stirring unit. 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 unit so as to inject air along the direction in which the electrode material is introduced, an air pressure supply unit that provides air pressure to each air nozzle, and a regulator that adjusts the air pressure supplied to each air nozzle. In one example, the air pressure supply unit may include an air pump, and the regulator can adjust the pressure of the air injected from the air nozzles (air pressure) by adjusting the air flow rate.

[0021] The plurality of air nozzles may be spaced apart from one another along the circumferential direction of the inlet of the stirring section.

[0022] The vibrating section may also include an air turbine vibrator.

[0023] The control unit may be configured to operate the air injection unit and the vibration unit during a feeding mode in which the electrode material is fed into the stirring unit.

[0024] Furthermore, in the throwing mode, the control unit can operate the air injection unit so that air is injected at a first operating pressure that is lower than the internal pressure of the stirring unit.

[0025] In addition, in the input mode, the first operating pressure may be 0.1 MPa to 0.6 MPa.

[0026] Furthermore, 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 in the closing mode.

[0027] The electrode material transport system may also include a material supply section having an outlet section that supplies the electrode material to the stirring section, and a piping section that connects the outlet section and the inlet section and guides the transport of the electrode material from the material supply section to the stirring section.

[0028] The piping section may include a first pipe connected to the agitator, a second pipe connected to the material supply section, and a vibration reduction tube provided on the second pipe.

[0029] The first pipe and the second pipe may be connected via a clamp. The first pipe may constitute an inlet of the agitator, and the second pipe may constitute an outlet of the material supply unit.

[0030] The air injection unit and the vibration unit may be provided on the first pipe. In one example, the air injection unit may be provided to inject air into the first pipe, and the vibration unit may be provided to apply vibration to the first pipe.

[0031] The electrode material transport system may also include an air knocker attached to the second pipe and configured to strike the second pipe in the electrode material feeding mode.

[0032] The control unit may be configured to operate the air injection unit and the vibration unit continuously and to operate the air knocker at predetermined time intervals during the charging mode.

[0033] The vibration damping tube may be made of a silicone material and may be provided to surround a portion of the second pipe.

[0034] The electrode material transport system may also include a vent pipe connected to the agitator. The control unit may be configured to open the vent pipe to the outside in the charging mode. In the charging mode, air pressure injected from the air injection unit may be applied to the inside of the agitator, thereby increasing the pressure inside the agitator. At this time, the pressure inside the agitator can be maintained constant by opening the vent pipe to the outside. A solenoid valve may be provided in the vent pipe.

[0035] Furthermore, when the pressure in the stirring unit decreases in the throwing mode, the control unit can operate the air injection unit so that air is injected at a second operating pressure higher than the first operating pressure. [Effects 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 agitator, clogging of the inlet by electrode material during the mixing process can be prevented. In particular, by injecting air into the inlet of the agitator during the electrode material feeding mode, aggregation of powdered electrode material can be prevented.

[0038] Furthermore, air is jetted from the air nozzle in the direction in which the electrode material is fed, pushing out the powdered electrode material in the feeding direction and feeding the powdered electrode material into the stirring section.

[0039] Furthermore, in the electrode material introduction mode, by applying vibration to the inlet of the stirring section, it is possible to prevent the electrode material from adhering to the inner surface of the inlet.

[0040] Furthermore, clogging of the inlet of the stirring section by the electrode material can be prevented, thereby shortening the transport time of the electrode material and improving the productivity of the slurry.

[0041] Furthermore, it is possible to minimize errors in the area of ​​electrode material input due to clogging, and it is also possible to minimize errors in measuring the electrode material. [Brief explanation of the drawings]

[0056] The air injection unit 140 is provided to be capable of fluidly moving with the interior of the inlet unit 131. The air injection unit 140 is provided to inject air at a predetermined air pressure from the interior of the inlet unit 131. 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 the injection pressure.

[0057] FIG. 6 is a diagram for explaining one operating state of the electrode material transport system 100 according to one embodiment of the present invention, and FIG. 7 is an enlarged view of the inlet portion 131 shown in FIG.

[0058] The air spraying unit 140 may include a plurality of air nozzles 141 to 144 arranged in the inlet 131 so as to spray air along the charging 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 of the air nozzles 141 to 144 and supplying air pressure to each of the air nozzles 141 to 144, and a regulator 145 for adjusting the air pressure supplied to each of the air nozzles 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 (air pressure) of the air injected from the air nozzles 141 to 144 by adjusting the flow rate of air.

[0060] Each of the air nozzles 141 to 144 may be provided in the inlet portion 131 at a distance from the vibration portion 150. The plurality of air nozzles 141 to 144 may be arranged at intervals along the circumferential direction of the inlet portion 131 of the stirring portion .

[0061] 6 and 7, the plurality of air nozzles 141 to 144 can be provided in the inlet portion 131 so that the air injection direction A1 is aligned with the electrode material input direction F1.

[0062] The air pressure supply unit 149 is connected to each of the air nozzles 141 to 144, and the air pressure supply unit 149 supplies air pressure to each of the air nozzles 141 to 144 in the electrode material 50 supply mode.

[0063] The electrode material transport system 100 may also include a material supply unit 110 having an outlet unit 111 that supplies the electrode material 50 to the agitator 130, and the material supply unit 110 may include a hopper. The material supply unit 110 may also store the 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] The electrode material transport system 100 may also include a piping section 170 that connects the outlet section 111 and the inlet section 131 and guides the electrode material 50 from the material supply section 110 to the agitation section 130 for transport.

[0065] The piping unit 170 may include a first pipe 175 connected to the agitation unit 130, a second pipe 171 connected to the material supply unit 110, and a vibration reduction tube 173 provided in the second pipe 171. The first pipe 175 and the second pipe 171 may be connected via a clamp 177.

[0066] An outlet 111 may be provided at the bottom of the material supply unit 110, and the outlet 111 is a passage through which the electrode material 50 is discharged from the material supply unit 110. In addition, an inlet 131 through which the electrode material 50 is introduced may be provided at the top of the stirring unit 130. In this case, the first pipe 175 may constitute the inlet 131 of the stirring unit 130, and the second pipe 171 may constitute the outlet 111 of the material supply unit 110.

[0067] In such a structure, the electrode material 50 in the material supply unit 110 can be fed into the agitation unit 130 by passing through the second pipe 171 and the first pipe 175 in this order.

[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 can be configured to operate the air injection unit 140 and the vibration unit 150 during a feeding mode in which the electrode material 50 is fed into the stirring unit 130.

[0070] Furthermore, in the addition mode, the control unit 190 can operate the air injection unit 140 to inject air at a first operating pressure that is lower than the pressure inside the agitation unit 130. In one example, in the addition mode, the first operating pressure can be 0.1 MPa to 0.6 MPa. Alternatively, the first operating pressure can be 0.3 MPa to 0.4 MPa.

[0071] During the electrode material 50 feeding mode, the air injection section 140 injects air into the electrode material 50 flowing through the inlet section 131, thereby dispersing the electrode material 50 into a powder form and pushing the electrode material 50 out in the electrode material feeding direction F1.

[0072] The electrode material transport system 100 may also include a vent pipe 210 connected to the agitator 130. The control unit 190 may be configured to open the vent pipe 210 to the outside O during an electrode material 50 introduction mode. During the electrode material 50 introduction mode, air pressure injected from the air injection unit 140 may be applied to the inside of the agitator 130, thereby increasing the pressure within the agitator 130. At this time, the pressure within the agitator 130 can be maintained 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] Meanwhile, a filter may be provided on the vent pipe 210. Therefore, the fluid discharged from the stirring unit 130 along the vent pipe 210 is discharged to the outside of the transfer system 100 after passing through the filter.

[0074] 4, the vibration unit 150 may be provided outside the inlet unit 131. The vibration unit 150 may be provided to apply vibration to the first pipe 175, and the vibration unit 150 may be provided to apply vibration outside the first pipe 175.

[0075] Furthermore, the vibration section 150 can be disposed apart from each of the air nozzles 141-144.

[0076] Furthermore, the vibration unit 150 is provided to provide a predetermined magnitude of vibration Fv to the inlet 131. The intensity of the vibration Fv generated by the vibration unit 150 may be in the range of 1 kgf to 60 kgf. The intensity of the vibration Fv generated by the vibration unit 150 may be in the range of 20 kgf to 25 kgf. That is, the control unit 190 can control the operation of the vibration unit 150 so that vibration is applied at an intensity of 1 kgf to 60 kgf during the electrode material 50 feeding mode.

[0077] The vibrating unit 150 may also include an air turbine vibrator. The air turbine vibrator is a device that uses compressed air as a power source to apply vibration to the inlet unit 131. In one example, the air turbine vibrator is a known device that generates vibration force by rotating an internal rotary turbine gear.

[0078] The vibration unit 150 applies vibration Fv to the inlet 131 in the charging mode for the electrode material 50. When the vibration 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 in the charging mode for the electrode material 50, 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 described 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 has the function of 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 metal material having rigidity.

[0081] Furthermore, the first pipe 175 is detachably coupled to the second pipe 171 by a clamp 177, and the first pipe 175 may be made of a rigid metallic material.

[0082] The electrode material transport system 100 may include an air knocker 180 attached to the second pipe 171 and configured to strike the second pipe 171 in the electrode material 50 supply mode.

[0083] The air knocker 180 can be provided in the second pipe 171, and the air knocker 180 has the function of striking the second pipe 171 during the electrode material 50 feeding mode, thereby preventing the powdered 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, it can be a vibration impactor that removes the electrode material 50 adhering to the inner surface of the second pipe 171 using an indirect impact method based on the reaction between compressed air and the magnetic force of a magnetic piston.

[0085] When the air knocker 180 is activated, the force of the air knocker 180 striking the second pipe 171 generates vibrations in the second pipe 171. If the vibrations generated by the air knocker 180 are transmitted to the agitator 130, the agitator 130 may malfunction.

[0086] To prevent this, the vibration reduction tube 173 may be provided to surround a portion of the second pipe 171. The vibration reduction tube 173 may be made of a silicone material. The vibration reduction 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 operations 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] The control unit 190 controls the operation of the material supply unit 110 in a mode for introducing the electrode material 50 so that the electrode material 50 is introduced into the inlet 131 via the outlet 111 of the material supply unit 110. Furthermore, the control unit 190 operates the stirring unit 130 in a mode for introducing the electrode material 50, and opens the vent pipe 210 to the outside.

[0089] In the charging mode, the electrode material 50 discharged from the material supply unit 110 is transported along the piping unit 170, passes through the inlet unit 131, and is charged into the stirring unit .

[0090] Depending on the characteristics of the electrode material 50, clogging of the inlet section 131 may occur. To solve this problem, the control section 190 controls the operation of the air injection section 140 and the vibration section 150 so that air pressure and vibration Fv are provided to the inlet section 131 (first piping) during the feeding mode in which the electrode material 50 is fed into the stirring section 130.

[0091] The control unit 190 may be configured to continuously operate the air injection unit 140 and the vibration unit 150 and to operate the air knocker 180 at predetermined time intervals during the electrode material 50 injection mode. In one example, during the electrode material 50 injection mode, 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 vibration Fv having an intensity of 1 kgf to 60 kgf is applied to the inlet 131 during the electrode material 50 charging mode.

[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 agitation unit 130 during the electrode material 50 injection mode.

[0094] In addition, in the input mode, if the pressure inside the agitating unit 130 decreases while air is being supplied at a first operating pressure lower than the internal pressure of the agitating unit 130, the control unit 190 can operate the air injection unit 140 to inject air at a second operating pressure higher than the first operating pressure.

[0095] Specifically, during the electrode material 50 feeding mode, while the pressure of the stirring unit 130 is maintained constant (the pressure at this time is referred to as the "set pressure"), the air injection unit 140 is operated to supply air at a first operating pressure, and when the pressure of the stirring unit 130 becomes lower than the set pressure, the air injection unit 140 can be operated to inject air at a second operating pressure higher than the first operating pressure.

[0096] If the electrode material 50 adheres to the inside of the first pipe 175, the air pressure supplied through the air spray unit 140 may not be properly transmitted to the agitator 130, which may result in a decrease in pressure within the agitator 130. In this case, the control unit 190 can eliminate the clogging phenomenon by operating the air spray unit 140 to spray air at a second operating pressure higher than the first operating pressure. In addition, the control unit 190 can increase the vibration intensity of the vibration unit 150 when the pressure in the agitator 130 becomes lower than the set pressure.

[0097] Meanwhile, when the pressure in the agitating unit 130 exceeds the set pressure, the control unit 190 can interrupt the feeding mode and stop the operations of the air spraying unit 140 and the vibration unit 150.

[0098] The preferred embodiments of the present invention described above have been disclosed for illustrative purposes, and those skilled in the art having ordinary skill in the art will be able to make various modifications, changes, and additions within the spirit and scope of the present invention, and such modifications, changes, and additions should be considered to fall within the scope of the following claims.
