Description

TECHNICAL FIELD

[0001] The present application relates to the field of battery manufacturing, in particular to an automatic adjusting device for different thickness batteries and expansion and contraction of a horizontal terminal. BACKGROUND

[0002] In the process of manufacturing lithium batteries, the lithium batteries need to be continuously charged and discharged to adjust and test the performance of the lithium batteries. In the charging and discharging process, a pressing mechanism is generally used, which includes positive and negative electrode needle plate assemblies that can be opened and closed towards each other, and the positive and negative electrode needle plate assemblies are horizontally mirror-imaged arranged. In the charging and discharging process, the lithium batteries are arranged in the accommodation space between the spacers to form a queue. The probes are arranged in a queue 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 probes contact the poles of the lithium batteries to charge and discharge the lithium batteries.

[0003] In order to stabilize and reliably charge and discharge the lithium batteries, attention needs to be paid to the stability of the pressing between the poles of the battery and the probe, that is, the projection position of the probe and the pole of the lithium battery in the vertical direction needs to be coincident. If the position of the probe and the pole of the lithium battery deviates, the probe cannot effectively contact the pole of the lithium battery, which affects the charging and discharging of the lithium battery.

[0004] At the same time, in the conventional battery capacity distribution equipment, the restraining tray cannot be compatible with the battery with large deviation of incoming material, and cannot provide a constant pressure for the battery during work. Moreover, when the battery expands during the capacity distribution process, it cannot be positioned dynamically, which will affect the displacement of the battery and the probe, thereby affecting the performance and appearance of the battery. The conventional capacity distribution equipment adopts a spraying type fire extinguishing, and after the battery catches fire, an automatic trigger spraying system is used to extinguish the fire by gas first and then by water. This fire extinguishing method cannot completely reduce the internal heat of the battery, which is easy to cause secondary fire of the battery, thereby causing great safety hazards to the equipment and plant.

[0005] The invention patent with publication number CN 117810511A discloses a submerged type charging and discharging mechanism. The battery tray is placed on the middle frame of the three-layer structure of the mechanism top frame, middle frame and bottom frame, and the obliquely downward probes for charging and discharging are arranged on the middle frame of the mechanism. The middle frame of the mechanism is pushed into the water tank assembly by the fire extinguishing cylinder, and the entire battery tray and the middle frame of the mechanism are immersed to isolate air, so as to achieve the purpose of safe fire extinguishing. In actual operation, the probes still in the charging and discharging process are sunk into the water tank assembly, which will cause safety hazards and increase unnecessary equipment replacement steps, which is not conducive to reducing production cost. At the same time, the ordinary probes used in the invention are difficult to accurately align the poles of the batteries on the battery tray under the pushing of the cylinder, and external workers often need to manually adjust the position of the battery tray, which is easy to cause poor contact between the probes and the batteries.

[0021] More specifically, the top of the needle plate assembly 214 is provided with a current connector 206 connected to an external circuit and a adapter plate 207.

[0022] More specifically, the water tank assembly 3 comprises a water tank body 301; the water tank body 301 is provided with a water inlet 302 and a water overflow port 303 for preventing the water level from being too high on the side, and a water outlet 304 for draining water on the bottom; the valve structure at the front of the water tank body 301 can be opened to facilitate the removal and replacement of the submerged equipment.

[0023] Before the battery tray 6 is placed, the spacing between the feeding component 400 and the lifting platform 408 is reduced by the feeding cylinder 407, the feeding pulley 4001 on the feeding component 400, the infrared temperature sensor 406 and the tool power supply needle 403 pass through the through hole 409 on the lifting platform 408, and the upper surface of the lifting platform 408 is exposed.

[0024] When starting to feed, the battery tray 6 is placed into the feeding component 400 from the feeding roller 13 at the front end of the rack frame 19 by the external feeding mechanism, and after the battery tray 6 is pushed in, it is conveyed backward by the feeding pulley 4001 located at the top of the lifting platform 408 and is limited by the limiting 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 feeding cylinder 407, the feeding pulley 4001 passing through the lifting platform 408 and contacting 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 pushes out to clamp the battery tray 6 between the clamping cylinder 105 and the lifting platform 408. Then, the probe mechanism 2 is pushed by the needle plate movement cylinder 11 to press-fit contact with the pole of the battery on the battery tray 6, and charging and discharging is carried out.

[0025] During the charging and discharging of the battery, when the temperature of the battery tray 6 is too high and a fire occurs, the infrared temperature sensor 406 detects the temperature anomaly and transmits a fire alarm signal to the upper computer. Then, the upper computer controls the submerged cylinder 401, the piston rod of the submerged cylinder 401 fixed to the rack frame 19 pushes down to push the lifting platform 408, the battery tray 6 and the feeding component 400 together into the water tank assembly 3, and the probe mechanism 2 and the rack frame 19 remain in place and are not submerged. The battery tray 6 completes fire extinguishing by isolating air, and the external worker opens the valve at the rear end of the water tank assembly 3 to replace the submerged components.

[0026] When the needle plate movement cylinder 11 pushes the probe 2 to approach the battery tray 6, the probe 2001 of the probe mechanism 2 is precisely matched with the battery pole 601 of the battery tray 6. The needle plate movement 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 matched with the tray clamping head 602 at the front end of the battery tray, and the uniform distribution rod joint 2003 on the probe component is matched with the remaining tray clamping head 602 of the battery tray. At this time, the guide block 201 is in contact with the tray clamping head 602 at the front end, and the probe component 200 behind is pulled to slide 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 maintains the initial position. The longer four uniform distribution rod joints 2003 on the probe component 200 at the rear are first in contact with the tray clamping head 602 of the battery tray 6, and press the uniform distribution rod joints 2003 of the remaining probe components to be matched with the remaining tray clamping heads 602 one by one, so as to complete the accurate matching of the probe 2001 and the battery pole 601.

[0027] The technical effect of the present application is that the lifting platform for preventing the battery tray from being submerged for fire extinguishing is separated from the middle frame of the rack, and only the battery tray, the lifting platform and the feeding component are submerged for fire extinguishing by the external staff, without submerging the charging and discharging probe and the entire middle frame of the rack, thereby improving the safety of the equipment, reducing the components that need to be cleaned, and thereby saving the time and cost of equipment maintenance; by establishing one-to-one follow-up positioning of the probe and the battery, it is ensured that the probe is always aligned with the electrode of the battery when the battery expands or shrinks during charging and discharging, and the probe effectively contacts the electrode, thereby ensuring the working quality of the battery charging and discharging.
