Description

Technical Field

[0001] The invention relates to the field of battery manufacturing, and in particular to a horizontal terminal fixed pressure and thickness self-adapting regulating device suitable for battery formation. Background Art

[0002] During the manufacturing process of lithium batteries, lithium batteries need to be continuously charged and discharged to adjust and test the performance of lithium batteries. In the charging and discharging process, a pressing mechanism is generally used. The pressing mechanism includes positive and negative electrode needle plate assemblies that can be opened and closed toward each other. The positive and negative electrode needle plate assemblies are arranged horizontally in mirror images. During charging and discharging, the lithium battery is arranged in the accommodation space between the spacers to form a queue. The probe queue is arranged on the top frame, and the probe queue is located on the left and right of the lithium battery queue. When the needle plate assembly is closed, the probe contacts the pole of the lithium battery to charge and discharge the lithium battery.

[0003] In order to ensure stable and reliable charging and discharging of lithium batteries, it is necessary to pay attention to the stability of the pressing between the battery pole and the probe, that is, the vertical projection position of the probe and the lithium battery pole needs to coincide. If the position of the probe and the lithium battery pole deviates, the probe will not be able to effectively contact the lithium battery pole, affecting the charging and discharging of the lithium battery.

[0004] At the same time, in conventional battery capacity separation equipment, the restraint tray is not compatible with batteries with large deviations in the incoming batteries, and cannot provide a constant pressure for the batteries during operation. Moreover, when the batteries expand during the capacity separation process, they cannot be positioned dynamically, which will affect the displacement of the batteries and the probes, thereby affecting the battery performance and appearance. Traditional conventional capacity separation equipment uses a spray-type fire extinguishing method. After the battery catches fire, an automatic triggering spray system is used to first extinguish the fire with gas and then start water spraying to extinguish the fire. This fire extinguishing method has the problem that the internal heat of the battery cannot be completely reduced, which can easily lead to secondary fires in the battery, thus posing a great safety hazard to the equipment and factory buildings.

[0005] The invention patent with publication number CN 117810511A discloses a submerged charging and discharging mechanism, in which a battery tray is placed on a mechanism middle frame in a three-layer structure having a mechanism top frame, a middle frame, and a bottom frame, and a probe for charging and discharging is set on the mechanism middle frame. The mechanism middle frame is sunk into a water tank assembly by the push of a fire extinguishing cylinder, and the air is isolated by immersing the entire battery tray and the mechanism middle frame, thereby achieving the purpose of safe fire extinguishing. In actual operation, sinking the probe that is still in the charging and discharging process into the water tank assembly will lead to safety hazards, and increase unnecessary equipment replacement steps, which is not conducive to reducing production costs. At the same time, the ordinary probe used in the invention is difficult to accurately align the poles of the battery on the battery tray under the push of the cylinder, and external staff are often required to manually adjust the position of the battery tray, which is prone to poor contact between the probe and the battery.

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

[0026] When loading begins, the battery tray 6 is placed into the loading component 400 from the loading roller 13 at the front end of the frame middle frame 19 through the external loading mechanism. After the battery tray 6 is pushed in, it is transported backward through the feeding pulley 4001 located at the top of the lifting platform 408 and is limited by the limit block 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 are separated from each other under the push of the loading cylinder 407. The feeding pulley 4001 that passes through the lifting platform 408 and contacts the bottom of the battery tray 6 descends together with the feeding component 400 and no longer contacts the battery tray 6. At this time, the battery tray 6 is completely placed on the lifting platform 408. Then, the piston rod of the tray clamping cylinder 105 on the top frame component 10 is pushed out to clamp 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 and contact the battery pole 601 on the battery tray 6 for charging and discharging.

[0027] During the process of charging and discharging the battery, when the temperature of the battery tray 6 is too high and a fire occurs, the infrared temperature sensor 406 detects the abnormal temperature and transmits a fire alarm signal to the upper computer. Then, the upper computer controls the sinking cylinder 401, and the piston rod of the sinking cylinder 401 fixed to the middle frame of the mechanism is pushed downward, pushing the lifting platform 408, the battery tray 6 and the feeding component 400 to sink into the water tank assembly 3 together, while the probe mechanism 2 and the middle frame 19 of the mechanism remain in place and are not submerged. The battery tray 6 completes the fire extinguishing by isolating the air, and the external staff opens the valve at the rear end of the water tank assembly 3 to replace the submerged components.

[0028] When the needle plate motion cylinder 11 pushes the probe 2 to approach the battery tray 6, the probe 2001 of the probe mechanism 2 and the battery pole 601 of the battery tray 6 are precisely aligned one by one. The needle plate motion cylinder 11 pushes the probe mechanism 2 to contact the battery pole 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 dividing rod fitting 2003 on the probe component is aligned with the remaining tray clamps 602 of the battery tray. At this time, the guide block 201 is in contact with the frontmost tray clamp 602, and the probe component 200 at the rear 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 queue of the guide block and the probe component remains in the initial position. The four longer dividing rod parts 2003 on the rear probe component 200 first contact the tray clamp 602 of the battery tray 6, squeezing the dividing rod parts 2003 of the remaining probe components to align with the remaining tray clamps 602 one by one, thereby completing the accurate alignment of the probe 2001 and the battery pole 601.

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

[0030] The technical effect of the present invention is that the lifting platform used to prevent the battery tray from sinking into water for fire extinguishing is separated from the rack middle frame. During fire extinguishing, only the battery tray, the lifting platform and the feeding components are sunk into water and replaced by external staff. There is no need to sink the charging and discharging probes and the entire rack middle frame, which improves the safety of the equipment and reduces the parts that need to be cleaned, thereby saving time and cost for equipment maintenance.

The battery tray 6 completes the fire extinguishing by isolating the air, and the external staff opens the valve at the rear end 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 rack middle frame 19. During fire extinguishing, only the battery tray 6, the lifting platform 408 and the feeding component 400 need to be submerged in water and replaced by external staff. There is no need to submerge the charging and discharging probe component 200 and the entire rack middle frame 19, which improves the safety of the equipment and reduces the number of components that need to be cleaned.

[0077] Embodiment 3

[0078] On the basis of the second embodiment, this embodiment adds a tray constant pressure mechanism 5 of the battery tray 6, so that when the thickness of the battery changes during the charging and discharging process, a stable pressure is maintained on the battery.

[0079] Reference Figure 2 , Figure 14-16 In this embodiment, the battery tray 6 to which the probe 2001 is docked comprises a rectangular tray bottom frame 603, a vertical front fixing plate 600 is provided at the front end of the tray bottom frame 603, and a vertical rear fixing plate 607 is provided at the rear end; the front fixing plate 600 is parallel to the rear fixing plate 607, and is connected by a longitudinal lining guide shaft 608; a plurality of tray lining plates 611 are longitudinally slidably provided on the lining guide shaft 608 through a card slot 609; a station for clamping batteries is reserved between adjacent tray lining plates 611;

[0080] A push plate 604 is provided on the tray inner lining plate 611 closest to the rear fixing plate 607, and a trapezoidal nut 605 and a restraining hole 610 are provided on the rear fixing plate 607; a longitudinal screw rod 606 passes through the trapezoidal nut 605 and contacts the push plate 604, and the screw rod 606 can move longitudinally and push the push plate 604 by rotating in the trapezoidal nut 605; a tray clamp 602 is provided on the top of the clamping slot 609, which can be laterally connected to the equalizing rod fitting 2003, and battery poles 601 are provided at both ends of the battery in the horizontal direction;

[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 clamped between the tray inner lining plates 611, so as to ensure the stability of the charging and discharging process. The tray constant pressure mechanism 5 includes a restrainer 500. The restrainer 500 includes a restraining guide shaft 5001. The front end of the restraining guide shaft 5001 is connected to the 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 in sequence. The slider fixing plate 502 is connected to an electric cylinder 501, and the electric cylinder 501 is connected to an external mechanism; the slider fixing plate 502 is connected to the rack middle frame 19 through the electric cylinder fixing plate 503.

[0082] In order to avoid a larger deviation between the front-end dividing rod assembly 2003 and the tray clamp 602 of the battery tray 6, the dividing rod assembly 2003 of several probe components 200 at the rear end is slightly longer than the dividing rod assembly 2003 of the other probe components 200, so that the dividing rod assembly 2003 at the rear end is initially aligned with the battery pole 601 and then pushes the front dividing rod assembly 2003 forward to ensure guiding compatibility.

[0083] When the battery tray 6 is docked with the restraint 500 during the charging and discharging process: the electric cylinder 501 evenly distributes the thrust to the four restraint guide shafts 5001 through the connecting block 5003, and the four restraint guide shafts 5001 then disperse the force to the push plate 604; the pressure condition of the battery is monitored in real time through the pressure sensor 5004, and then the pressure applied to the push plate 604 is adjusted by the electric cylinder 501 to ensure that the battery remains stable under pressure after charging and expansion.

[0084] The combination of the battery tray 6 and the restraint guide shaft 5001 realizes battery expansion in the restrained state so that the probe 2001 moves along with the battery expansion; the restraint guide shaft 5001 adjusts the pressure of the battery in real time through the feedback of the pressure sensor 5004, thereby preventing the battery from being damaged and affecting the battery charging and discharging performance due to the expansion of the battery thickness during the charging and discharging process, and preventing indentations on the battery appearance.

[0085] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
