Description

Technical Field

[0001] This invention relates to a main unit for acquiring pressure data and a tray for housing the same, and more specifically, to a main unit for acquiring pressure data and a tray for housing the same, which can measure the flatness, parallelism, pressure magnitude and resistance of a pressure plate that applies pressure to a pressurized object, and can accurately and easily acquire and provide pressure data of such pressure plate. Background Technology

[0002] Typically, rechargeable batteries can be charged and can be made in large capacities. Representative rechargeable batteries include nickel-cadmium batteries, nickel-metal hydride batteries, and lithium-ion batteries. Some of these rechargeable batteries can be made into flexible pouch-type shapes, which offers the advantage of relatively free shape design.

[0003] This type of secondary battery pack contains battery cells internally, and a polymer outer material corresponding to the pack surrounds the battery cells. Therefore, it consists of electrodes, a pack, and battery cells. Furthermore, when the internal structure of the secondary battery pack is damaged or destroyed, compromising insulation, the battery cells cannot maintain their normal operating voltage, which may lead to low voltage and potentially cause swelling of the battery cells.

[0004] Therefore, the inspection of secondary battery cell packs, including the insulation wires, is necessary to fundamentally eliminate defects. As a related prior art, Korean Patent No. 10-1896218, "Simultaneous Inspection Device for Multiple Secondary Battery Cell Packs," is proposed. It includes: a support member for support; a movable member facing the support member; multiple pressure plates arranged side-by-side between the support member and the movable member, which are engaged with each other at adjustable intervals by moving the movable member back and forth, with secondary battery cell packs inserted into the gaps formed between them; a guide member for guiding the pressure plates to move in the interval adjustment direction; electrode modules fixed to the pressure plates in a manner where multiple modules are arranged between each pressure plate, moving with the pressure plates, and connected to each electrode portion of the secondary battery cell pack located in the gaps to apply or receive current; and a pressure drive unit for moving the movable member forward and backward, thereby allowing the secondary battery cell packs between the pressure plates to be inspected from both sides. The battery cell pack is pressurized and depressurized. The electrode module includes: a fixing component fixed to one side of the pressure plate; an electrode actuator fixed to the fixing component and arranged along the interval adjustment direction, having a movable tip for adjusting the interval; fixing plates respectively fixed to the movable tip; and electrodes respectively arranged on the fixing plates in an opposing manner, achieving surface contact with both sides of the electrode portion of the secondary battery cell pack through the drive of the electrode actuator. The electrode module is disposed in a mounting groove formed in the pressure plate. A guide hole extending along the width direction of the secondary battery cell pack is formed in the fixing component. The fixing position is changed along the width direction by a fixing bolt inserted into the guide hole and tightened into the inner side of the mounting groove.

[0005] As described above, the existing technology can only improve the reliability of inspecting secondary battery cell packs when the pressure applied to the cell packs by each pressure plate is uniformly distributed across the entire pressure surface. Therefore, pressure data of the pressure surface of the pressure plate is required. This necessity is not limited to secondary battery cell packs but applies to all devices that apply pressure to objects. Therefore, the Korea Institute of Industrial Technology Planning and Evaluation (KIT) of the Ministry of Trade, Industry and Energy aims to address this problem through project (2410002718) in the "Second Phase New Support Project for the Development of Materials and Components Technology in the Secondary Battery Field in 2024": "Development of a self-diagnostic KIT integrated production system for the activation process with automatic loading and unloading for improving secondary battery productivity."

Detailed Implementation

[0026] This invention can be implemented in various ways with different modifications; therefore, a specific embodiment is illustrated in the figures and explained accordingly. Furthermore, this invention is not limited to this specific embodiment, but should be understood to include all modifications, equivalent technical solutions, or alternative technical solutions within the technical concept of this invention.

[0027] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Identical structural elements will be assigned the same reference numerals, and repeated descriptions thereof will be omitted.

[0028] Figure 1 This is a perspective view illustrating a main unit for acquiring pressurized data and a tray for housing it, according to an embodiment of the present invention. Figure 2 To illustrate a perspective view of a main unit for acquiring pressurized data according to an embodiment of the present invention, Figure 3 To illustrate a rear perspective view of the main unit for acquiring pressurized data according to an embodiment of the present invention, Figure 4 This is a structural diagram of a main unit for acquiring pressurized data according to an embodiment of the present invention.

[0029] Reference Figures 1 to 4 According to an embodiment of the present invention, the main unit 100 for acquiring pressurized data may include a unit body 110, an electronic pressure-sensitive paper 120, a communication unit 140, and a battery 150.

[0030] The cell body 110 is inserted between the pressure plates in place of the pressurized object. For example, the pressure plate may correspond to a plate that applies pressure to a cell pack of a secondary battery as mentioned in the prior art, but is not limited to this. For various purposes such as experimentation, measurement, and manufacturing, it may correspond to a plate that applies pressure to the pressurized object on one or both sides. In this case, the cell body 110 is loaded into the pressure position in place of such a pressurized object and is pressurized by the pressure plate.

[0031] The electronic pressure-sensitive paper 120 is laid flat on one side of the unit body 110 and in contact with the surface of the object being pressurized, outputting an electrical signal based on the distribution of pressure applied by the pressure plate. For example, the electronic pressure-sensitive paper 120 outputs an electrical signal that can be externally confirmed by measuring the applied pressure using multiple pressure sensors arranged in a two-dimensional plane on a planar component such as a thin film or sheet. For example, the pressure sensors can be various pressure sensing devices or apparatuses that can be formed multiple times on a planar component, including force-sensitive resistors (FSRs) arranged at predetermined intervals along the X and Y directions.

[0032] The communication unit 140 transmits the electrical signal output from the electronic pressure-sensitive paper 120 wirelessly. As an example, the communication unit 140 is a communication device that receives the electrical signal from the electronic pressure-sensitive paper 120 and directly transmits it to an external signal processing device that processes the output pressure value and pressure distribution. As another example, as shown in this embodiment, the communication unit 140 communicates with a router 250 (see reference 140). Figure 5 This is a communication device that uses router 250 as a medium to transmit signals to external signal processing equipment. The communication unit 140 can use various communication methods such as Bluetooth, Ultra-wideband (UWB), Zifeng, Wi-Fi, 3G, LTE, 5G, or Wi-Fi to communicate with external signal processing equipment or router 250.

[0033] As one example, the communication unit 140 directly converts the electrical signal of the electronic pressure-sensitive paper 120 into a wireless signal for transmission. As another example, it receives a transmission signal converted from the electrical signal of the electronic pressure-sensitive paper 130 by the controller 130, etc., and transmits it as a wireless signal. That is, the communication unit 140 can be solely responsible for transmitting the electrical signal of the electronic pressure-sensitive paper 130 as a wireless signal, or the controller 130, etc., can participate in the process, thereby enabling the communication unit 140 to operate in this manner.

[0034] The battery 150 provides the power required for the operation of the electronic pressure-sensitive paper 120 and the communication unit 140. It can be charged via a charging power source, which is supplied through a charging electrode 151 located at the lower end of the unit body 110. The controller 130, described later, can be implemented on a printed circuit board, which may also include a charging circuit for charging the battery 150.

[0035] The main unit 100 for acquiring pressurized data in one embodiment of the present invention may further include a housing 160, measuring electrodes 171 and 172, and a clamp 180.

[0036] The housing portion 160 has a plate-like structure so that it is located above the electronic pressure-sensitive paper 120 within the unit body 110. This allows the communication unit 140 and the controller 130 for notification operations to be housed internally, maintaining a compact structure together with the unit body 110. Furthermore, if necessary, the housing portion 160 can house a battery 150 internally. The communication unit 140 and the controller 130 are formed separately, or may be included in the controller 130. The controller 130 can control the power supply and operation of the electronic pressure-sensitive paper 120 and the communication unit 140 in accordance with operating signals or control signals received from the outside.

[0037] Measuring electrodes 171 and 172 are respectively formed protruding at both ends of the unit body 110 for measuring resistance. They can be a pair of positive and negative measuring electrodes 171 and 172, respectively, and are protruding to allow connection to external resistance measuring equipment, thus functioning as probes for such equipment. Measuring electrodes 171 and 172 are connected to a resistor with a known resistance value and can be connected to various types of resistance measuring equipment. When measuring resistance, calibration is performed based on the known resistance value.

[0038] The clamping parts 180 are respectively provided on both sides of the upper end of the unit body 110 in a clamping manner, and can have a flat structure that is conducive to clamping. These clamping parts 180 can provide a clamping location when a large number of main units 100 for acquiring pressurized data are respectively loaded between various pressurized plates by the clamping device. At least two or more of these clamping parts 180 are formed for stable clamping, and as shown in this embodiment, they can be arranged in a "..." shape based on the corner portions on both sides of the unit body 110. The shape of the character "".

[0039] Figure 5 To illustrate a perspective view of the main unit tray according to an embodiment of the present invention, Figure 6 To show a front sectional view of a main unit for acquiring pressurized data according to an embodiment of the present invention mounted on a main unit tray, Figure 7 This is a partial top view showing the state in which the main unit for acquiring pressurized data according to an embodiment of the present invention is mounted on the main unit tray.

[0040] Reference Figures 5 to 7 In one embodiment of the present invention, the main unit tray 200 is a tray in which multiple main units 100 for pressurized data acquisition are installed side by side. It may include a tray body 210 and a slit 220.

[0041] The inner side of the tray body 210 opens upwards, and for this purpose, an upper opening 211 is formed at the top, thereby allowing the main unit 100 for pressurized data acquisition to be in an open state through an upper opening. Furthermore, the tray body 210 can open to the side, thereby forming side openings 212 on both sides so that the main unit 100 for pressurized data acquisition housed inside can be confirmed.

[0042] Multiple slits 220 are arranged side by side so that the main unit 100 for pressurizing data acquisition can be vertically installed on the inside of the pallet body 210.

[0043] Slits 220 can be disposed between supports 221. The multiple supports 221 are vertically spaced on both sides of the bottom surface within the tray body 210. Anti-detachment portions 222 disposed on the outer side of each support 221 allow the penetration of measuring electrodes 171, 172 protruding from both sides of the unit body 110 while preventing the unit body 110 from passing through. Inlet / outlet guide portions 223, inclined downwards on both sides of the upper end of the anti-detachment portions 222, allow the measuring electrodes 171, 172 to be inserted between the anti-detachment portions 222. Figure 7As shown, the anti-detachment section 222 has a "T"-shaped planar structure together with the support 221 in order to allow the measurement electrodes 171 and 172 to pass through and prevent the unit body 110 from passing through. This structure intersects with the end of the support 221. Thus, when the main unit 100 for pressurized data acquisition is located inside the gap 220 formed between the supports 221, the measurement electrodes 171 and 172 are allowed to pass through the narrowed gap between the anti-detachment sections 222.

[0044] The main unit tray 200 of one embodiment of the present invention may further include: a spacer support 230 for spacer support above the unit body 110; a router 250 for providing electrical signals of the electronic pressure-sensitive paper 120 to an external signal processing device via communication in the main unit 100 for pressurized data acquisition; and a probe pin 240 for providing charging power to the battery 150 of the main unit 100 for pressurized data acquisition housed inside.

[0045] The spacer support 230 supports the lower sides of the unit body 110 on the bottom surface within the tray body 210, thereby forming a receiving space 231 between the unit body 110 and the bottom surface within the tray body 210. The spacer support 230 may be provided with anti-detachment steps 222 to engage with the grooves 111 on the inner side where charging electrodes 151 are formed, which are formed downwards on the lower end of the unit body 110 for charging the battery 150. Therefore, the spacer support 230 separates and supports the lower sides of the unit body 110 from the bottom surface of the tray body 210, thereby forming a receiving space 231 for accommodating the router 250. The anti-detachment steps 222, which can engage with the grooves 111 formed on both sides of the lower end of the unit body 110, prevent the probe pins 240 from detaching laterally from the charging electrodes 151 of the unit body 110 and keep them connected.

[0046] Router 250 can be installed within housing space 231 and can wirelessly transmit the electrical signals of electronic pressure-sensitive paper 120, which are transmitted through communication with communication unit 140, to external signal processing equipment. For this purpose, router 250 can use various communication methods such as Wi-Fi, 3G, LTE, 5G, or Wi-Fi to act as a medium for communication between communication unit 140 and external signal processing equipment. In the external signal processing equipment, the electrical signals of electronic pressure-sensitive paper 120 are processed according to a defined process, and the magnitude of the pressure applied by the pressure plate, flatness, parallelism, etc., measured by electronic pressure-sensitive paper 120, are output through a display device or a designated terminal.

[0047] The probe pins 240 connect and support each charging electrode 151 for charging the battery 150 to both sides of the lower end of the cell body 110, thereby providing power for charging. The probe pins 240 are arranged in two rows along the arrangement direction of the cell bodies 110 on the bottom surface of the tray body 210, allowing power to be supplied to the charging electrodes 151 located on both sides of the lower end of the cell body 110. The probe pins 240 have a telescopic structure within a defined vertical range and can have an internal spring that elastically returns upwards, thereby stably maintaining contact with the charging electrodes 151 and minimizing impact on the charging electrodes 151. Furthermore, the probe pins 240 supply power to the charging electrodes 151 via a cable extending from the tray body 210, which is then converted into a power distribution for charging.

[0048] According to the main unit for acquiring pressure data and the tray for accommodating it as described above, the flatness, parallelism, pressure magnitude and resistance of the pressure plate that applies pressure to the pressurized object can be measured, and the pressure data of such pressure plate can be accurately and easily acquired and provided.

[0049] Furthermore, according to the present invention, through the aforementioned effects, the present invention can improve the reliability of various subsequent operations related to the pressurization process, such as inspection, measurement, monitoring, or manufacturing.

[0050] As described above, the present invention has been illustrated with reference to the accompanying drawings. Various modifications can be made without departing from the scope of the technical concept of the invention. Therefore, the scope of the present invention is not limited to the described embodiments, but is defined by the scope of the invention claims and equivalent content.
