Description

Technical Field

[0001] This invention relates to the field of battery manufacturing, and in particular to a device for adaptive adjustment of horizontal terminal pressure and thickness used in battery formation. Background Technology

[0002] During lithium battery manufacturing, continuous charging and discharging is required to adjust and test the battery's performance. In the charging and discharging process, a pressing mechanism is typically used. This mechanism includes positive and negative electrode plate assemblies that can open and close in opposite directions. These assemblies are horizontally mirrored. During charging and discharging, the lithium batteries are placed in the space between the separators, forming a queue. Probe queues are arranged on the top frame, positioned to the left and right of the lithium battery queue. When the plate assemblies close, the probes contact the lithium battery terminals, charging and discharging the battery.

[0003] For stable and reliable charging and discharging of lithium batteries, it is crucial to ensure the stability of the contact between the battery terminals and the probe. Specifically, the vertical projections of the probe and the lithium battery terminals must coincide. If the probe and the lithium battery terminals are misaligned, the probe will fail to effectively contact the battery terminals, affecting the charging and discharging process.

[0004] Meanwhile, in conventional battery grading equipment, the restraint tray cannot accommodate batteries with large deviations from the incoming materials. It cannot provide a constant pressure to the batteries during operation, and when the batteries expand during the grading process, it cannot be positioned accordingly, affecting the displacement of the battery and probes, thus impacting battery performance and appearance. Traditional conventional grading equipment uses a spray-type fire suppression system. After a battery catches fire, the system automatically triggers a gas extinguishing system followed by a water spray extinguishing system. This method fails to completely reduce the internal heat of the battery, easily leading to secondary fires and posing significant safety hazards to the equipment and factory.

[0005] Chinese patent application CN 117810511A discloses a submersion charging and discharging mechanism. The mechanism places a battery tray on the middle frame of a three-layer structure consisting of a top frame, middle frame, and bottom frame. An angled probe for charging and discharging is positioned on the middle frame. A fire-extinguishing cylinder pushes the middle frame into a water tank assembly, immersing the entire battery tray and the middle frame to isolate it from the air and achieve safe fire extinguishing. However, in practice, submerging a probe still charging or discharging into the water tank assembly poses a safety hazard and increases unnecessary equipment replacement steps, hindering cost reduction. Furthermore, the ordinary probes used in this invention are difficult to accurately align with the battery terminals on the battery tray under the cylinder's push, often requiring manual adjustment of the battery tray position by external personnel, which can easily lead to poor contact between the probe and the battery. Summary of the Invention

[0006] To address the aforementioned issues, this invention proposes a device for adaptive adjustment of horizontal terminal pressure and thickness. The concept lies in increasing the accuracy of battery docking during charging and discharging by separating the platform of the lifting battery tray from the frame and improving the probe mechanism that docks with the battery tray, thereby reducing the damage to the device caused by submerged fire extinguishing.

[0010] When an abnormal battery temperature is detected, the infrared temperature sensor 406 transmits a battery fire alarm signal to the industrial control computer. The industrial control computer sends a command signal to the submersible cylinder 401, which pushes the feeding component 400, the lifting platform 408, and the battery tray 6 into the water tank assembly 3.

[0015] The probe component initial position holding device 213 includes an initial positioning plate 2130 slidably mounted on the probe slide rail 212 and an initial position cylinder 2134 fixed on the frame of the needle plate assembly 2. The cylinder extension shaft 2132 of the initial position cylinder 2134 passes through the shaft hole of the cylinder lifting seat 2133 on the initial position cylinder 2134. The end of the cylinder extension shaft 2132 is provided with a shoulder to prevent the cylinder extension shaft 2132 from being pulled away from the cylinder lifting seat 2133. The initial positioning plate 2130 is connected to the guide block 201. In the initial position, the initial position cylinder 2134 pulls the initial positioning plate 2130, so that the probe component 200 is held in position. After the initial position cylinder 2134 is activated, the cylinder extension shaft 2132 is extended, the initial positioning plate 2130 and the guide block 201 are released, and the probe component 200 is pulled back to its original position by the tension spring 203.

[0016] More specifically, the battery tray 6 docked by the probe 2001 includes a rectangular tray base frame 603. The front end of the tray base frame 603 is provided with a vertical front fixing plate 600, and the rear end is provided with a vertical rear fixing plate 607. The front fixing plate 600 and the rear fixing plate 607 are parallel and connected by a longitudinal inner liner guide shaft 608. Several tray inner liner plates 611 are longitudinally slidable on the inner liner guide shaft 608 through slots 609. A work station for clamping batteries is left between adjacent tray inner liner plates 611.

[0017] A push plate 604 is provided on the inner lining plate of the tray closest to the rear fixing plate. A trapezoidal nut 605 and a restraint hole 610 are provided on the rear fixing plate 607. A longitudinal lead screw 606 passes through the trapezoidal nut 605 and contacts the push plate 604. The lead screw 606 can move longitudinally by rotating within the trapezoidal nut 605 and push the push plate 604. The top of the slot is provided with a tray clamp 602 that can be laterally connected to the equalizing rod assembly 2003. Battery terminals 601 are provided at both ends of the battery in the lateral direction.

[0018] A restraint device 500 is respectively installed in the restraint hole 610. The restraint device 500 includes a restraint guide shaft 5001. The front end of the restraint guide shaft 5001 is connected to a push plate, and the rear end is connected to a slider fixing plate through a reinforcing plate 5002, a pressure sensor 5004 and a connecting block 5003 in sequence.

[0020] More specifically, a position sensor 2004 is provided on the top surface of the probe slider 2006. When the battery expands, it is reflected in the probe component 200. The movement of the probe component 200 will cause the position sensor 2004 to move. The detection result is fed back to the host computer. If the battery expansion value exceeds the maximum displacement threshold, the system will sound an alarm.

[0021] More specifically, the probe slider 2006 is equipped with a temperature probe 2002 facing the battery tray 6. The temperature probe 2002 senses the temperature of the battery and uploads it to the host computer.

[0022] More specifically, to avoid a large deviation between the front-end equalizing rod assembly and the tray clamp 602 of the battery tray 6, the equalizing rod assemblies 2003 of several probe components 200 at the rear end are slightly longer than the equalizing rod assemblies 2003 of the other probe components 200. This allows the rear-end equalizing rod assembly 2003 to initially align with the battery terminal 601 and then push the front equalizing rod assembly 2003 forward, ensuring guiding compatibility.

[0023] More specifically, the equalizing rod assembly 2003 includes an equalizing rod fixing seat 20033; the equalizing rod fixing seat 20033 is connected to the probe component 200, the equalizing rod fixing seat 20033 is provided with an equalizing rod baffle 20034 on the outer side, and the inner side is connected to the positioning block 20031 through the equalizing rod 20030. The positioning block 20031 has a V-shaped jaw that can mate with the tray clamp head 602 of the battery tray 6, and an equalizing rod spring 20032 is sleeved on the equalizing rod 20030.

[0024] More specifically, the peripheral rack is equipped with an electrical cabinet 73 containing a control center PLC; an alarm light 75 is provided on the top of the peripheral rack, and a horizontal slide rail 72 is provided on the top of the peripheral rack, with a sliding touch screen 71 on the horizontal slide rail 72; the peripheral rack is equipped with several safety doors 74 at the same height.

[0025] Before placing the battery tray, the present invention reduces the distance between the feeding component 400 and the lifting platform 408 by the feeding cylinder 407. The feeding pulley 4001 on the feeding component 400, the infrared temperature sensor 406 and the tooling power-taking needle 403 pass through the through hole on the lifting platform 408, exposing the upper surface of the lifting platform 408.

[0026] When feeding begins, the battery tray 6 is fed into the feeding component 400 from the feeding roller 13 at the front end of the frame 19 via an external feeding mechanism. After being pushed in, the battery tray 6 is conveyed backward by the feeding pulley 4001 located at the top of the lifting platform 408 and limited by the limit stop 402. After the infrared temperature sensor 406 detects that the battery tray 6 is in place, the lifting platform 408 and the feeding component 400 separate under the push of the feeding cylinder 407. The feeding pulley 4001, which passes through the lifting platform 408 and contacts the bottom of the battery tray 6, descends with the feeding component 400 and no longer contacts the battery tray 6. At this time, the battery tray 6 is completely flat on the lifting platform 408. Then, the piston rod of the tray clamping cylinder 105 on the top frame component 10 is pushed out, clamping the battery tray 6 between the clamping cylinder 105 and the lifting platform 408. Then, the needle plate movement cylinder 11 pushes the probe mechanism 2 to press against the battery terminals 601 on the battery tray 6 for charging and discharging.

[0027] During battery charging and discharging, if the battery tray 6 overheats and a fire occurs, the infrared temperature sensor 406 detects the abnormal temperature and transmits a fire alarm signal to the host computer. Then, the host computer controls the submersible cylinder 401, whose piston rod, fixed to the frame, pushes downwards, causing the lifting platform 408, battery tray 6, and feeding component 400 to sink into the water tank assembly 3. The probe mechanism 2 and the frame frame 19 remain in place and are not submerged. The battery tray 6 extinguishes the fire by isolating it from air. External personnel then open the valve at the rear of the water tank assembly 3 to replace the submerged components.

[0028] When the needle plate movement cylinder 11 pushes the probe 2 closer to the battery tray 6, the probe 2001 of the probe mechanism 2 is precisely aligned with the battery terminals 601 of the battery tray 6. The needle plate movement cylinder 11 pushes the probe mechanism 2 to contact the battery terminals 601 on the battery tray 6, so that the guide block 201 is aligned with the frontmost tray clamp 602 of the battery tray, and the equalizing rod assembly 2003 on the probe component is aligned with the remaining tray clamps 602 of the battery tray. At this time, the guide block 201 contacts the frontmost tray clamp 602, and the probe component 200 behind it is pulled forward along the probe slide rail 212 by the tension spring 203; the initial position cylinder 2134 pulls the guide block 201 through the cylinder extension shaft 2132 and the initial positioning plate 2130, so that the guide block and the probe component are in the initial position. The four longer dividing rods 2003 on the rear probe component 200 first contact the tray clamp 602 of the battery tray 6, pressing the dividing rods 2003 of the remaining probe components one by one with the remaining tray clamps 602, thereby completing the accurate alignment of the probe 2001 and the battery terminal 601.

[0029] When the battery tray 6 docks with the restraint 500 during charging and discharging: the electric cylinder 501 distributes the thrust evenly to the four restraint guide shafts 5001 through the connecting block 5003. The four restraint guide shafts 5001 then distribute the force to the push plate 604. The pressure sensor 5004 monitors the pressure on the battery in real time, and then the electric cylinder 501 adjusts the pressure applied to the push plate 604 to ensure that the battery remains under pressure and stable after charging and expansion.

[0030] The technical advantages of this invention are as follows: the lifting platform used to prevent the battery tray from sinking in water during fire extinguishing is separated from the frame. During fire extinguishing, only the battery tray, lifting platform, and feeding components sink in water and are replaced by external personnel. There is no need to sink the charging and discharging probes and the entire frame, which improves the safety of the equipment and reduces the number of parts that need to be cleaned, thereby saving time and cost for equipment maintenance.

The top frame component 10 lowers the tray clamping cylinder 105, and the clamping cylinder 105 and the lifting platform 408 clamp and fix the battery tray 6 from the top and bottom respectively. The needle plate movement cylinder 11 pushes the probe mechanism 2 to press and contact the battery terminal 601 on the battery tray 6 to perform charging and discharging.

[0062] When the battery tray 6 overheats and a fire occurs: the infrared temperature sensor 406 detects the abnormal temperature and transmits a fire alarm signal to the host computer. The host computer controls the submersible cylinder 401, and the piston rod of the submersible cylinder 401, which is fixed to the middle frame 19 of the frame, pushes the lifting platform 408, the battery tray 6, and the feeding component 400 into the water tank assembly 3. The probe mechanism 2 and the middle frame 19 of the frame remain in place and are not submerged. The battery tray 6 extinguishes the fire by isolating the air. External personnel open the valve at the rear of the water tank assembly 3 to replace the submerged components.

[0063] During this process, the lifting platform 408 used to submerge the battery tray for fire extinguishing is separated from the frame 19. During fire extinguishing, only the battery tray 6, the lifting platform 408, and the feeding component 400 need to be submerged and replaced by external personnel. There is no need to submerge the charging and discharging probe component 200 and the entire frame 19, which improves the safety of the equipment and reduces the number of parts that need to be cleaned.

[0064] Example 2

[0065] This embodiment improves the probe mechanism 2 based on the adaptive adjustment device for horizontal terminal pressure and thickness in Embodiment 1, so that it can adaptively follow the thickness change of the battery during the formation process.

[0066] Refer to Figure 5- Figure 9 , Figure 12 The probe mechanism 2 includes a needle plate mounting base 211 and a needle plate assembly 214; the needle plate assembly 214 is detachably coupled to the needle plate mounting base 211, and one side of the needle plate assembly 214 forms a longitudinal working surface that interacts with the battery tray 6; the end of the longitudinal working surface near the lead screw 606 mounted on the battery tray 6 is defined as the forward direction; the side of the needle plate assembly 214 facing the battery tray 6 is the inward direction, and the opposite side is the outward direction;

[0067] The bottom of the needle plate mounting base 211 is slidably mounted on the horizontally arranged needle plate movement slide rail 210 so that the longitudinal working surface of the needle plate assembly 214 approaches or moves away from the battery tray 6; the needle plate movement slide rail 210 is mounted on the top of the needle plate slide rail fixing plate 208, and the needle plate slide rail fixing plate 208 is connected to the frame middle frame 19.

[0068] The longitudinal working surface of the needle plate assembly 214 is provided with a longitudinal probe slide rail 212, and the probe component 200 is slidably mounted on the probe slide rail 212; the front part of the probe slide rail 212 is provided with a probe component initial position holding device 213 and a guide block 201, and the guide block 201 is provided with an inclined surface that cooperates with the tray clamp 602 of the tray inner liner plate 611 at the front end of the battery tray 6; the probe component 200 is provided with a spring pin 2005, and a tension spring 203 is connected between the spring pins 2005 on adjacent probe components 200; the frontmost probe component 200 is connected to the guide block 201 by a tension spring 203.

[0069] The probe component 200 includes a probe slider 2006, which is slidably mounted on the probe slide rail 212. The probe slider 2006 is provided with a dividing rod assembly 2003 that cooperates with the tray clip 602 of the tray liner 611 and a probe 2001 that aligns with the battery terminal 601. Both the dividing rod assembly 2003 and the probe 2001 are positioned toward the battery tray 6.

[0070] The probe component initial position holding device 213 includes an initial positioning plate 2130 slidably mounted on the probe slide rail 212 via a positioning slider 2131, and an initial position cylinder 2134 fixed on the frame of the needle plate assembly 214. The cylinder extension shaft 2132 of the initial position cylinder 2134 passes through the shaft hole of the cylinder lifting seat 2133 on the initial position cylinder 2134. The end of the cylinder extension shaft 2132 is provided with a shoulder to prevent the cylinder extension shaft 2132 from being pulled away from the cylinder lifting seat 2133. The initial positioning plate 2130 is connected to the guide block 201. In the initial position, the initial position cylinder 2134 pulls the initial positioning plate 2130, so that the probe component 200 is held in position. After the initial position cylinder 2134 is activated, the cylinder extension shaft 2132 is extended, the initial positioning plate 2130 and the guide block 201 are released, and the probe component 200 is pulled back to its original position by the tension spring 203.

[0071] The needle plate mounting base 211 is provided with a longitudinal pull-out needle plate slide rail 202. The needle plate assembly 214 is slidably mounted on the pull-out needle plate slide rail 202 and can be detached from the pull-out needle plate slide rail 202.

[0072] A position sensor 2004 is installed on the top surface of the probe slider 2006. When the battery expands, it is reflected in the probe component 200. The movement of the probe component 200 will cause the position sensor 2004 to move. The detection result is fed back to the host computer. If the battery expansion value exceeds the maximum displacement threshold, the system will sound an alarm.

[0073] The probe slider 2006 is equipped with a temperature probe 2002 facing the battery tray 6. The temperature probe 2002 senses the temperature of the battery and uploads it to the host computer.

[0074] The equalizing rod assembly 2003 includes an equalizing rod fixing seat 20033; the equalizing rod fixing seat 20033 is connected to the probe component 200, the equalizing rod fixing seat 20033 is provided with an equalizing rod baffle 20034 on the outer side, and the equalizing rod 20030 is connected to the positioning block 20031 on the inner side. The positioning block 20031 has a V-shaped jaw that can mate with the tray clamp head 602 of the battery tray 6. An equalizing rod spring 20032 is sleeved on the equalizing rod 20030 so that the equalizing rod 20030 can be reset after displacement due to contact with the tray clamp head 602.

[0075] In some embodiments, the top of the needle plate assembly 214 is provided with a current line connector 207 and an adapter plate 206 for connecting an external current line; the front end of the needle plate assembly 214 is provided with a temperature acquisition module 205 and a needle plate handle 204.

[0076] The probe component 200 connects with the tray clamp 602 via the guide block 201 and the equalizing rod assembly 2003, enabling real-time alignment of the battery terminal 601 and the probe 2001. It can automatically adapt to batteries of different thicknesses, ensuring stable and reliable electrical contact between the probe 2001 and the battery terminal 601. This prevents the battery terminal 601 from misaligning with the probe 2001 due to expansion during battery charging and discharging, thus ensuring high-quality battery charging and discharging.

[0077] Example 3

[0078] Based on Embodiment 2, this embodiment adds a constant pressure mechanism 5 to the battery tray 6, so that it maintains a stable pressure on the battery when the battery thickness changes during charging and discharging.

[0079] Reference Figure 2 , Figures 14-16 In this embodiment, the battery tray 6 docked by the probe 2001 includes a rectangular tray bottom frame 603. The front end of the tray bottom frame 603 is provided with a vertical front fixing plate 600, and the rear end is provided with a vertical rear fixing plate 607. The front fixing plate 600 and the rear fixing plate 607 are parallel and connected by a longitudinal inner liner guide shaft 608. Several tray inner liner plates 611 are longitudinally slidably disposed on the inner liner guide shaft 608 through slots 609. A work station for clamping batteries is left between adjacent tray inner liner plates 611.

[0080] A push plate 604 is provided on the tray inner liner 611 closest to the rear fixing plate 607. The rear fixing plate 607 is provided with a trapezoidal nut 605 and a restraint hole 610. A longitudinal lead screw 606 passes through the trapezoidal nut 605 and contacts the push plate 604. The lead screw 606 can rotate longitudinally within the trapezoidal nut 605 and push the push plate 604. The top of the slot 609 is provided with a tray clamp 602 that can be laterally connected to the equalizing rod assembly 2003. The battery is provided with battery terminals 601 at both ends laterally.

[0081] The front end of the battery tray 6 is connected to the tray constant pressure mechanism 5. The function of the tray constant pressure mechanism 5 is to use constant pressure to press the battery between the inner lining plates 611 of the tray, thereby ensuring the stability of the charging and discharging process. The tray constant pressure mechanism 5 includes a restraint 500, which includes a restraint guide shaft 5001. The front end of the restraint guide shaft 5001 is connected to a push plate 604, and the rear end is connected to a slider fixing plate 502 through a reinforcing plate 5002, a pressure sensor 5004, and a connecting block 5003. The slider fixing plate 502 is connected to an electric cylinder 501, which is connected to an external mechanism. The slider fixing plate 502 is connected to the frame middle frame 19 through the electric cylinder fixing plate 503.

[0082] To avoid excessive deviation between the front-end equalizing rod assembly 2003 and the tray clamp 602 of the battery tray 6, the equalizing rod assemblies 2003 of several probe components 200 at the rear end are slightly longer than the equalizing rod assemblies 2003 of the other probe components 200. This allows the rear-end equalizing rod assembly 2003 to initially align with the battery terminal 601 and then push the front equalizing rod assembly 2003 forward, ensuring guiding compatibility.

[0083] When the battery tray 6 docks with the restraint 500 during charging and discharging: the electric cylinder 501 distributes the thrust evenly to the four restraint guide shafts 5001 through the connecting block 5003, and the four restraint guide shafts 5001 then distribute the force to the push plate 604; the pressure sensor 5004 monitors the pressure on the battery in real time, and then the electric cylinder 501 adjusts the pressure applied to the push plate 604 to ensure that the battery remains under pressure and stable after charging and expansion.

[0084] The combination of battery tray 6 and restraint guide shaft 5001 enables battery expansion under restraint, causing probe 2001 to move along with the battery expansion; the restraint guide shaft 5001 adjusts the battery pressure in real time through feedback from pressure sensor 5004, preventing damage to the battery and affecting its charging and discharging performance due to battery thickness expansion during charging and discharging, and preventing indentations on the battery appearance.

[0085] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
