Description

Technical Field

[0001] This invention belongs to the field of lithium-ion battery production technology, specifically relating to a space-saving lithium-ion battery voltage regulator and voltage regulation method. Background Technology

[0002] Lithium iron phosphate (LiFePO4) batteries are highly safe and stable, and are used in many fields. After formation, the open-circuit voltage can reach 3.65~3.75V. After capacity testing and evaluation, they need to be left to stand for 36~48 hours to allow the open-circuit voltage to stabilize at 3.25~3.27V before packaging and shipping. When a factory's annual battery production reaches 1GWh or more, the area required for battery resting increases significantly, increasing factory space and manufacturing costs.

[0003] Utility model CN221714798U discloses a battery settling device, including a platform with a turntable on its upper surface. Multiple base plates are equidistantly mounted in a ring along the edge of the turntable's upper surface. Multiple vertically arranged plates for limiting the position of trays are mounted on the end of each base plate facing the center of the turntable. Two limiting plates are symmetrically mounted on the upper surface of each base plate. Multiple first insertion slots, equidistant from top to bottom, are formed on the opposite faces of the two limiting plates on each base plate. A tray for supporting bipolar plates is inserted between two first insertion slots on the same horizontal line. Two sets of temporary storage mechanisms for temporarily storing trays are mounted on the upper surface of the platform. A transfer mechanism for moving the trays between storage positions is provided on the upper side of the turntable. The structure of this battery settling device results in a wider production workshop and a longer flow of battery clamps between adjacent settling modules, leading to a longer overall settling time and reduced production efficiency.

[0004] Utility model CN222146311U discloses a differential pressure settling device, including a first settling line, a second settling line, and a conveying device. The first and second settling lines are arranged parallel to each other. The first settling line includes a first lifting module, a first starting point settling module, an intermediate settling module, and an ending point settling module connected sequentially from left to right. The second settling line includes a second lifting module and a second starting point settling module connected sequentially from left to right. The conveying device is located at the right end of the ending point settling module and the second starting point settling module. This utility model can reduce the width of the production workshop, but the space occupied by the settling device cannot be adjusted according to the number of formed batteries. Summary of the Invention

[0005] To address the aforementioned technical problems in the prior art, this invention provides a space-saving lithium-ion battery voltage regulator and a voltage regulation method.

[0006] This invention provides a space-saving lithium-ion battery voltage regulator platform, comprising: a support frame, the support frame including at least two sub-support sections, the two sub-support sections having a telescopic cooperation structure that can extend and retract to adjust the length of the entire support frame, each sub-support section being provided with a support foot; a chain plate, including several support plates connected in sequence, the chain plate being laid on the support frame, at least one of the two ends of the chain plate being wound or unwound by a winding mechanism.

[0007] Furthermore, the bracket comprises two sub-brackets, which has the simplest and most reliable structure and the lowest manufacturing cost. While satisfying the basic length adjustment function, it avoids the complexity and instability that may be brought about by multi-segment structures, making it highly practical.

[0008] Furthermore, the telescopic structure includes a first support rod mounted on one of the sub-supports and arranged along the length of the support, and a second support rod mounted on the other sub-support and arranged along the length of the support. The first support rod has an axially arranged sliding groove, and the second support rod has a sliding rod that mates with the sliding groove. Through the precise fit between the sliding groove and the sliding rod, the telescopic adjustment process is made smoother and more stable, effectively preventing the sub-supports from shaking or misaligning during telescopic movement. This improves the overall rigidity and load-bearing capacity of the lithium-ion battery voltage regulator, and extends the service life of the equipment.

[0009] Furthermore, the sidewall of the slide groove is provided with pin holes, and the slide rod is provided with positioning holes at intervals. The two sub-supports are fixed together by positioning pins passing through the pin holes and the corresponding positioning holes. The pins fixing the support to the positioning holes provide a firm mechanical lock, ensuring that the length of the support remains stable when bearing weight, effectively preventing the slide rod from accidentally sliding in the slide groove, and improving the safety and reliability of the equipment.

[0010] Furthermore, the sub-support with the slide rod is equipped with pulleys on its support legs. By adding pulleys to the support legs, the originally bulky sub-support can be moved easily, making the extension and retraction of the sub-support easier.

[0011] Furthermore, one of the sub-supports is equipped with the winding mechanism, one end of the chain plate is wound or unwound by the winding mechanism, and the other end is fixed to another sub-support.

[0012] Furthermore, the winding mechanism is mounted on the support leg of the sub-support, and a transition roller is also provided on the outer side of the sub-support above the winding mechanism. Placing the winding mechanism on the support leg and adding the transition roller optimizes the lever arm structure, making winding more effortless.

[0013] Furthermore, the winding mechanism includes a main shaft with at least two gears. The chain plate, at least on a portion of its support plate near the winding mechanism, has corresponding toothed grooves. During winding, the toothed grooves on the support plate engage with the gears. At least one end of the main shaft also has a rocker arm. Through the precise meshing of the gears and toothed grooves, smooth, synchronous, and powerful winding and unwinding actions are achieved, effectively preventing slippage and jamming. The rocker arm design provides a labor-saving and reliable operation method, improving the accuracy and efficiency of adjustment.

[0014] The present invention also provides a space-saving lithium-ion battery voltage stabilization method. Using the above-mentioned space-saving lithium-ion battery voltage stabilization platform, the space-saving lithium-ion battery voltage stabilization method includes the following steps: the number of lithium-ion batteries to be stabilized is determined by winding or unwinding through the winding mechanism, and the length of the chain plate and the support is adjusted.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention saves workshop space by extending the length of the lithium-ion battery voltage regulator platform according to the number of formed batteries, reducing equipment investment and representing an excellent lean manufacturing method and battery pack voltage regulation method. When not in use, the lithium-ion battery voltage regulator platform can be retracted to its shortest state, greatly saving storage and transportation space. The core structure of this invention is a mechanical telescopic mechanism, which is cost-effective, easy to promote, and the telescopic adjustment process is simple, time-saving, and labor-saving.

Detailed Implementation

[0027] like Figures 1-10 As shown, a space-saving lithium-ion battery voltage regulator includes a support and a chain plate 2.

[0028] The support includes at least two sub-support sections 1, preferably two sections 1, which is the simplest and most reliable structure with the lowest manufacturing cost. While meeting the basic length adjustment function, it avoids the complexity and instability that may be caused by multi-section structures, making it highly practical. The two sections 1 have a telescopic cooperation structure that can be extended and retracted to adjust the length of the entire support. Each sub-support 1 is equipped with a support foot 11.

[0029] The telescopic mechanism includes a first support rod 12 mounted on one of the sub-supports 1 and arranged along the length of the support, and a second support rod 13 mounted on the other sub-support 1 and arranged along the length of the support. The first support rod 12 has an axially arranged groove 121, and the second support rod 13 has a sliding rod 131 that mates with the groove 121. The precise fit between the groove 121 and the sliding rod 131 makes the telescopic adjustment process smoother and more stable, effectively preventing the sub-support 1 from shaking or misaligning during telescopic movement, improving the overall rigidity and load-bearing capacity of the lithium-ion battery voltage regulator, and extending the service life of the equipment.

[0030] The slide 121 has pin holes 122 on its side wall, and the slide rod 131 has positioning holes 132 spaced apart. The two sub-supports 1 are fixed together by positioning pins 133 passing through the pin holes 122 and the corresponding positioning holes 132. The pins fixing the support to the positioning holes 132 provide a strong mechanical lock, ensuring that the length of the support remains stable when under load, effectively preventing the slide rod 131 from sliding accidentally in the slide 121, and improving the safety and reliability of the equipment.

[0031] The sub-support 1 with slide bar 131 has a pulley 111 on its support leg 11. By adding pulley 111 to the support leg 11, the originally bulky sub-support 1 can be moved easily, making the extension and retraction of the sub-support 1 easier.

[0032] The chain plate 2 includes several support plates 21 connected in sequence. The chain plate 2 is laid on the support. At least one end of the chain plate 2 is wound or unwound by the winding mechanism 14.

[0033] The winding mechanism 14 is mounted on one of the sub-supports 1. One end of the chain plate 2 is wound or unwound by the winding mechanism 14, and the other end is fixed to another sub-support 1.

[0034] Specifically, the winding mechanism 14 is mounted on the support leg 11 of the sub-support 1, and a transition roller 15 is also provided on the outer side of the sub-support 1 above the winding mechanism 14. Placing the winding mechanism 14 on the support leg 11 and adding the transition roller 15 optimizes the lever arm structure, making winding easier. The transition roller 15 ensures a smooth transition of the chain plate 2 during extension and contraction, reducing friction and wear.

[0035] The winding mechanism 14 includes a main shaft 141 with at least two gears 142. The support plate 21 of the chain plate 2, at least a portion of which is close to the winding mechanism 14, has corresponding toothed grooves 22. During winding, the toothed grooves 22 on the support plate 21 engage with the gears 142. At least one end of the main shaft 141 also has a rocker arm 143. Through the precise meshing of the gears 142 and the toothed grooves 22, a smooth, synchronous, and powerful winding and unwinding action is achieved, effectively preventing slippage and jamming. The rocker arm 143 design provides a labor-saving and reliable operation method, improving the accuracy and efficiency of adjustment.

[0036] This embodiment also provides a space-saving lithium-ion battery voltage stabilization method. Using the above-mentioned space-saving lithium-ion battery voltage stabilization platform, the space-saving lithium-ion battery voltage stabilization method includes the following steps: the number of lithium-ion batteries to be stabilized is determined by winding or unwinding through the winding mechanism 14, and the length of the chain plate 2 and the support is adjusted.

[0037] The specific operation process is as follows: (1) Confirm the number and size of the lithium-ion batteries that need to be stabilized and placed for static treatment. Based on the size and number of batteries, estimate the effective bearing area of ​​the lithium-ion battery voltage stabilizer platform, and thus determine the approximate length of the lithium-ion battery voltage stabilizer platform that needs to be extended.

[0038] (2) The operator puts the positioning pin 133 in the pulled-out state to release the mechanical lock on the telescopic fit structure.

[0039] (3) The operator rotates the rocker arm 143 clockwise, which drives the main shaft 141 and its gear 142 to rotate. The gear 142 meshes with the tooth groove 22 of the support plate 21 on the chain plate 2, which smoothly and synchronously unfolds the chain plate 2 from the winding mechanism 14. At the same time, the force is transmitted to the sub-support 1 with the slide bar 131, which pushes the pulley 111 to roll away from the winding mechanism 14, so that the sub-support 1 with the slide bar 131 extends.

[0040] (4) When the length of the bracket and chain plate 2 reaches the target length determined in step (1), stop rotating the rocker arm 143, visually check whether the positioning hole 132 on the slide rod 131 is aligned with the pin hole 122 on the side wall of the slide groove 121, insert the positioning pin 133 into the aligned pin hole 122 and positioning hole 132 to achieve rigid mechanical locking between the two sub-brackets 1.

[0041] (5) Place the lithium-ion batteries that need to be left to stand one by one on the support surface of the unfolded chain plate 2.

[0042] (6) When it is necessary to shrink the lithium-ion battery voltage regulator, pull out the positioning pin 133, rotate the rocker arm 143 counterclockwise, and install the positioning pin 133 to fix it after determining the length.
