Description

Technical Field

[0001] The present invention relates to a water pressure measuring device and a water pressure analysis system, and more specifically, to a water pressure measuring device for measuring the water pressure of a cleaning liquid sprayed from a battery cleaning process equipment, and a water pressure analysis system for analyzing sensing data measured by the water pressure measuring device.

Background Art

[0002] A secondary battery is a battery that can be reused through charging even after discharge, and can be used as an energy source for small devices such as mobile phones, tablet PCs, and vacuum cleaners, and can also be used as an energy source for medium and large devices such as automobiles and smart grid ESSs (Energy Storage Systems).

[0003] Secondary batteries are applied to systems in the form of assemblies such as battery modules in which a number of battery cells are connected in series and parallel according to the requirements of the system, or battery packs in which battery modules are connected in series and parallel. In the case of medium and large devices such as electric vehicles, a high-capacity battery system in which a number of battery packs are connected in parallel can be applied to meet the required capacity of the corresponding device.

[0004] Secondary batteries can be classified into can-type batteries in which an electrode assembly is built into a cylindrical metal can, and pouch-type batteries in which an electrode assembly is built into a pouch-shaped case. Generally, cylindrical can-type batteries are known to have relatively large capacities and high structural stability.

[0005] A cylindrical battery cell is manufactured by housing a wound-type electrode assembly in a cylindrical can, injecting an electrolyte into the can, and then coupling a cap assembly having electrode terminals formed thereto to the open upper end of the can. A positive electrode terminal protruding in the central region of the upper end of the cap assembly can be formed, and a negative electrode terminal can be formed at other parts of the metal can. The cylindrical battery cell can be sealed through a crimping process after the cap assembly is coupled to the open upper end of the can.

[0006] During the manufacturing process of cylindrical battery cells, electrolyte may adhere to the electrode terminals or metal casing, which may cause the battery to corrode. To prevent corrosion caused by foreign matter, a cleaning solution (e.g., cleaning water) can be sprayed onto the outer surface of the battery cell during the cleaning process to remove the foreign matter.

[0007] Generally, a method of measuring the internal pressure of the pipes through which the cleaning fluid is sprayed is used to diagnose whether cleaning process equipment is spraying cleaning fluid at the intended water pressure. However, with this conventional method, errors can occur between the measured internal pressure of the pipe and the water pressure of the cleaning fluid discharged from the spray nozzle, limiting its reliability. Furthermore, if the internal pressure of all pipes through which the cleaning fluid is sprayed is measured, the design cost of the water pressure monitoring system increases significantly, and generally, only the internal pressure of one pipe is monitored.

[0008] Therefore, to solve the problems of these conventional technologies, there is a need for a water pressure measuring device and a water pressure analysis system using the same that can accurately measure the water pressure of the cleaning fluid sprayed from the battery cleaning process equipment and can be implemented at low cost. [Overview of the project] [Problems that the invention aims to solve]

[0034] Figure 1 is a reference diagram illustrating the battery cleaning process equipment.

[0035] Referring to Figure 1, the battery cleaning process equipment is equipped to remove foreign matter from the outer surface of the battery cell 10 by spraying cleaning fluid through multiple spray nozzles 20.

[0036] Each of the multiple battery cells 10 can be mounted on a carrier and transported to a position where multiple spray nozzles 20 are provided. Each of the multiple spray nozzles 20 is fixed in a predefined position and at a predefined angle, and can spray cleaning fluid toward the outer surface of each of the sequentially transported battery cells 10.

[0037] After the cleaning process using the cleaning equipment, the battery cell 10 is moved to the blower equipment, which removes the cleaning solution by spraying air onto the outer surface of the battery cell 10. Subsequently, the battery cell 10 is moved to the drying equipment, which dries the battery cell by spraying high-temperature air onto the outer surface of the battery cell 10.

[0038] For the cleaning process using the cleaning equipment to be effective, the cleaning fluid must be sprayed onto the outer surface of the battery cell 10 at a uniform water pressure. For example, if the cleaning fluid is sprayed at a relatively high water pressure only in a specific area, or at a relatively low water pressure only in a specific area, foreign matter formed on the outer surface of the battery cell cannot be completely removed.

[0039] To prevent such phenomena, it is necessary to precisely measure the water pressure of the cleaning fluid sprayed from each of the multiple spray nozzles 20 and calibrate the cleaning process equipment based on the measured values. To monitor the water pressure of the cleaning fluid, a method is generally used in which the water pressure is sensed inside the spray nozzle 20 or inside a tube connected to the spray nozzle 20, and the water pressure of the sprayed cleaning fluid is indirectly determined based on the sensed value. However, with such conventional technology, errors may occur between the measured sensed value and the water pressure of the cleaning fluid discharged from the spray nozzle 20, limiting the ability to precisely calibrate the cleaning process equipment. Furthermore, considering the design cost of the water pressure monitoring system, if the water pressure is measured for only one spray nozzle 20, it is not possible to grasp the water pressure distribution in all directions of the battery cell 10, making it difficult to utilize the sensed value for calibrating the cleaning process equipment.

[0040] The present invention was devised to solve the problems of the prior art described above, and proposes a water pressure measuring device having a shape corresponding to the housing of a battery cell and equipped with a plurality of water pressure measuring sensors on its outer surface, and a water pressure analysis system using the same. Hereinafter, various embodiments of the present invention will be described in detail with reference to Figures 2 to 6.

[0041] Figure 2 is a block diagram of a hydraulic analysis system according to an embodiment of the present invention.

[0042] Referring to Figure 2, the hydrostatic analysis system according to an embodiment of the present invention can be configured to include a hydrostatic measuring device 100 and a hydrostatic analysis device 200.

[0043] The water pressure measuring device 100 is a device that is introduced into the cleaning process equipment and measures the water pressure of the cleaning fluid sprayed from the spray nozzles of the cleaning process equipment.

[0044] The water pressure measuring device 100 has a shape corresponding to the housing of the battery cell and can be configured with a plurality of water pressure measuring sensors on its outer surface. That is, the water pressure measuring device 100 according to the present invention is manufactured to have the same shape as the battery cell being cleaned through the cleaning process, and is configured to measure the water pressure distribution of the cleaning liquid sprayed onto the outer surface of the actual battery cell through a plurality of water pressure measuring sensors provided on its outer surface.

[0045] The water pressure measuring device 100 can be configured to include a housing formed in the same shape as the housing of a battery cell, a plurality of water pressure measuring sensors provided on the outer surface of the housing, and a control device provided in the space inside the housing.

[0046] The control device located inside the housing is electrically connected to multiple water pressure measuring sensors and can collect sensing data. The collected sensing data can be transmitted to the water pressure analyzer 200 via a communication module located inside the housing. The detailed structure and operation of the water pressure measuring device 100 will be described later.

[0047] The water pressure measuring device 100 can be placed between actual battery cells being transported through a carrier of cleaning process equipment, and can be transported together with the actual batteries and sprayed with cleaning fluid, and can be configured to measure the water pressure of the cleaning fluid sprayed during the course of such a cleaning process.

[0048] The hydraulic pressure analyzer 200 is a computing device that receives hydraulic pressure sensing data from the hydraulic pressure measuring device 100 and analyzes the hydraulic pressure using the received hydraulic pressure sensing data. Here, the hydraulic pressure analyzer 200 generates hydraulic pressure distribution information (e.g., pressure profile, density distribution data, etc.) using the hydraulic pressure sensing data received from the hydraulic pressure measuring device 100, and can diagnose whether there is any abnormality in the cleaning process equipment (e.g., clogging of a specific spray nozzle, etc.).

[0049] Figure 3 shows a water pressure measuring device according to an embodiment of the present invention.

[0050] Referring to Figure 3, the water pressure measuring device 100 can be configured to include a housing 110, a plurality of water pressure measuring sensors 121, and a control device 131.

[0051] The housing 110 can be formed in a shape corresponding to the housing of the battery cell. For example, if the battery cell applied to the cleaning process equipment is a cylindrical battery cell of the 4680 standard (46 mm in diameter, 80 mm in height), the housing 110 of the water pressure measuring device 100 can be manufactured in the same standard shape (46 mm in diameter, 80 mm in height) as the actual cylindrical battery cell housing (metal can). By forming the housing 110 of the water pressure measuring device 100 in the same shape as the actual battery cell, the water pressure distribution of the cleaning solution sprayed onto the battery cell during the cleaning process can be measured more accurately.

[0052] Multiple water pressure measuring sensors 121 can be provided on the outer surface of the housing 110. Here, the water pressure measuring sensor 121 is a device that outputs sensing data corresponding to the pressure applied by the cleaning fluid. The water pressure measuring sensor 121 can be embodied in a variety of known pressure sensors or tactile sensors, such as capacitive sensors and piezoelectric sensors, but the scope of the present invention is not limited to these individuals.

[0053] Multiple water pressure measuring sensors 121 can be arranged in a fixed pattern at predefined positions. For example, as shown in Figure 3, multiple water pressure measuring sensors 121 can be arranged at regular intervals on the top, side, and bottom surfaces of the housing 110.

[0054] Multiple water pressure measuring sensors 121 can be fixedly coupled to a sensor support structure formed on a planar structure or a mesh structure. Here, the sensor support structure is configured to cover the outer surface of the housing 110, and the multiple water pressure measuring sensors 121 can be arranged on the outer surface of the housing 110.

[0055] The control device 131 is a device that collects water pressure sensing data output from multiple water pressure measuring sensors 121 and transmits the collected water pressure sensing data to the water pressure analyzer 200.

[0056] The control device 131 can be provided in the space inside the housing 110. The control device 131 can be fixedly coupled to a control board (e.g., a PCB board), and the control board can be fixedly coupled to the internal space inside the housing.

[0057] The control device 131 can be electrically connected to a plurality of water pressure measuring sensors 121 and configured to receive water pressure sensing data from the water pressure measuring sensors 121. For example, a connector electrically connected to each of the water pressure measuring sensors 121 can be formed on the control board and fastened to a connector mounting groove electrically connected to the control device 131, thereby electrically connecting the control device 131 and the water pressure measuring sensors 121.

[0058] The control device 131 can transmit the collected water pressure sensing data to the water pressure analyzer 200 via a communication module. For example, the control device 131 can be configured to transmit the water pressure sensing data to the water pressure analyzer 200 via a wireless communication module provided on the control board.

[0059] The housing 110 may be equipped with a power supply device for supplying power to each component of the water pressure measuring device 100. For example, a battery may be provided inside the housing 110 to supply power to each component, and a wireless charging device (e.g., a wireless charging coil) for charging the battery may be provided.

[0060] Figure 4 is an exploded perspective view of a water pressure measuring device according to an embodiment of the present invention, and Figure 5 is an unfolded view of a sensor support structure according to an embodiment of the present invention. Specifically, Figures 4 and 5 are concrete examples of a water pressure measuring device according to an embodiment of the present invention, and below, with reference to Figures 4 and 5, the structure and operation of various embodiments of the water pressure measuring device according to the present invention will be described in detail.

[0061] The housing 110 of the water pressure measuring device can be composed of a main body 111 and a cover 112. For example, referring to Figure 4, the cover 112 can be screw-connected to the top of the cylindrical main body 111 to create a seal. Here, the housing 110, into which the main body 111 and the cover 112 are connected, can be formed to have the same shape as an actual battery cell.

[0062] The sensor assembly 120 may consist of a plurality of water pressure measuring sensors 121, sensor support structures 122 to 124, and a connector 125.

[0063] Multiple water pressure measuring sensors 121 can be fixedly coupled to sensor support structures 122-124. Here, each of the multiple water pressure measuring sensors 121 can be fixedly coupled to a predefined position on the sensor support structure to form a certain pattern.

[0064] The sensor support structure can be formed in a shape corresponding to the housing 110 and configured to cover the outer surface of the housing 110. Here, as shown in Figure 5, the sensor support structure can be composed of an upper portion 122, a lower portion 124, and a side portion 123, and the upper portion 122, lower portion 124, and side portion 123 can be configured to face and contact the upper, lower, and side surfaces of the housing 110, respectively. Multiple water pressure sensors can be fixedly coupled to each of the upper portion 122, lower portion 124, and side portion 123 at regular intervals and distributed on the outer surface of the housing 110.

[0065] In the embodiment, the sensor support structures 122 to 124 can be formed as planar structures or mesh structures. For example, the upper surface 122, lower surface 124, and side surface 123 of the sensor support structure can be formed as planar structures, with a water pressure sensor fixedly coupled to one surface, and a conductor can be embedded in the planar structure so that the water pressure sensor and the connector 125 are electrically connected through the conductor. In another example, the upper surface 122, lower surface 124, and side surface 123 of the sensor support structure can be formed as mesh structures in which insulated wires form a mesh structure, and the water pressure sensor and the connector 125 can be electrically connected through the insulated wires.

[0066] In this embodiment, the sensor support structures 122-124 can be formed from an elastic material. According to this embodiment, the sensor support structures can be more easily coupled to the housing 110.

[0067] The control board 130 can be configured to be fixed in a specific position inside the housing 110. Here, as shown in Figure 4, the control board 130 can be configured to be fixed by sliding coupling to a guide rail G formed longitudinally on the inner surface of the main body 111.

[0068] One side of the control board 130 can be configured with a control device 131, a communication module, memory, a wireless charging receiver, and connector mounting grooves.

[0069] The control device 131 can collect water pressure sensing data output from multiple water pressure measuring sensors 121 and transmit the collected water pressure sensing data to the water pressure analyzer 200.

[0070] The control device 131 can be electrically connected to a plurality of water pressure measuring sensors 121 and configured to receive water pressure sensing data from the water pressure measuring sensors 121.

[0071] Referring to Figure 5, the connector 125 is configured to be electrically connected to each of the water pressure measuring sensors 121 and can extend to the side portions 123 of the sensor support structures 122-124. Also, referring to Figure 4, the main body portion 111 can have a through hole H formed on one side into which the connector can be inserted. Here, if the sensor assembly 120 is coupled so as to cover the outer surface of the housing 110, the connector 125 can be inserted into the through hole formed at a position corresponding to the connector 125 and fastened to a connector mounting groove (not shown) mounted on the control board 130. Terminals formed inside the connector mounting groove are configured to be electrically connected to the control device 131, and the control device 131 and the water pressure measuring sensor 121 can be electrically connected.

[0072] The control device 131 can transmit the water pressure sensing data received from the water pressure sensor to the water pressure analyzer 200 via a communication module. Here, the communication module can consist of a wireless communication module (for example, a Bluetooth module), and the control device 131 can transmit the water pressure sensing data to the water pressure analyzer 200 via the wireless communication module after the cleaning process is completed.

[0073] The housing 110 may be equipped with a power supply device for supplying power to each component of the water pressure measuring device 100. As shown in Figure 4, the power supply device may be configured by sequentially stacking and connecting a battery 141, a wireless charging coil cover 142, and a wireless charging coil 143. The battery 141 may be configured to be electrically connected to the control board 130 to supply power.

[0074] A waterproof packing 150 can be provided inside the housing 110 to prevent the inflow of cleaning fluid. As shown in Figure 4, the waterproof packing 150 is positioned at the joint between the main body 111 and the cover 112, and by sealing the housing 110 when the main body 111 and the cover 112 are joined, the inflow of cleaning fluid into the interior can be prevented.

[0075] Figure 6 is a flowchart of the operation of the hydraulic analysis method according to an embodiment of the present invention.

[0076] The water pressure measuring device 100 is mounted on a carrier of the cleaning process equipment and is sequentially transported along with the actual battery cells. When it is moved to the position of the spray nozzle, cleaning fluid is sprayed onto the water pressure measuring device 100 (S610).

[0077] The water pressure measuring device 100 collects water pressure sensing data generated through multiple water pressure measuring sensors distributed on its outer surface (S620).

[0078] The hydrostatic analyzer 200 receives hydrostatic sensing data from the hydrostatic measuring device 100 and uses the received hydrostatic sensing data to generate coordinate-specific hydrostatic pressure information defined on the outer surface of the battery cell (S630). Here, the hydrostatic analyzer 200 can identify the position of each hydrostatic measuring sensor based on the identifier of each hydrostatic measuring sensor, and can generate coordinate-specific hydrostatic pressure information based on the hydrostatic sensing value and the position coordinate corresponding to the sensing value. Here, the generated coordinate-specific hydrostatic pressure information may include pressure profiles and density distribution data.

[0079] The hydraulic pressure analyzer 200 can diagnose whether there is an abnormality in the cleaning process equipment based on the generated coordinate-specific hydraulic pressure information (S640). For example, if the hydraulic pressure at a specific location falls outside a predefined threshold range, it can be determined that an abnormality has occurred at that location and the corresponding injection nozzle.

[0080] According to the various embodiments of the present invention described above, the water pressure of the cleaning fluid sprayed from the battery cleaning process equipment can be accurately measured, and a water pressure measuring device and a water pressure analysis system can be realized at low cost.

[0081] Some aspects of the present invention have been described in the context of apparatus, but they can also be described by corresponding methods, where a block or apparatus corresponds to a method step or a feature of a method step. Similarly, aspects described in the context of a method can be described by corresponding blocks or items or features of corresponding apparatus. Some or all of the method steps can be carried out by (or using) hardware devices such as, for example, a microprocessor, a programmable computer, or an electronic circuit. In some embodiments, one or more of the most important method steps can be carried out by such devices.
