Description

Technical Field

[0001] This invention relates to the field of lithium battery winding device technology, specifically to a winding device for insulating tape for lithium battery packs. Background Technology

[0002] In the production and manufacturing process of lithium battery packs, several lithium batteries need to be arranged and combined to form a lithium battery pack. Insulating tape is used to wrap and secure the outer periphery of the lithium battery pack to prevent the lithium batteries from shifting or scattering during transportation and assembly, and to ensure the smooth progress of subsequent assembly processes.

[0003] Chinese Patent No. CN220796825U discloses a lithium battery pack winding fixture. This fixture, by setting a fixed collar, a rotatable movable collar, and a film mounting base, enables the winding of insulating tape by manually rotating the movable collar. Compared with the manual winding method, it can improve the speed and quality of tape winding.

[0004] However, the existing tooling has obvious limitations, with a low overall level of automation and integration: 1. Poor process coordination and low production efficiency: The existing tooling only has a single tape winding function. All processes before and after the lithium battery pack winding, such as transfer, orderly arrangement, placement of insulating layers between lithium batteries, and unloading and handling of heavy lithium battery packs after winding, all rely on manual operation. The material flow between processes is not smooth, the overall production steps are cumbersome, and the production efficiency of lithium battery packs is greatly reduced.

[0005] 2. Manual operation poses many risks and product quality is unstable: The insulation layer is placed manually, which makes it easy for it to be missed.

Detailed Implementation

[0033] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0034] See Figures 1 to 13 As shown, a winding device for insulating tape of lithium battery packs includes a winding and stacking device installed below the winding fixture 2. The winding and stacking device includes a horizontal conveyor 3, a lifting and pushing device 4, an arrangement adjustment device 5, a limiting and blocking device 7, a displacement adjustment device 8, and a layer feeding device 6. The horizontal conveyor 3 is positioned between two lithium battery conveyors 21, with its input end connected to the output end of one lithium battery conveyor 21 and its output end connected to the input end of the other lithium battery conveyor 21. The lifting and pushing device 4 is installed below the horizontal conveyor 3. The lifting and pushing device 4 has a movable... The moving ends are set on both sides of the horizontal conveyor 3. The lifting and pushing device 4 is used to limit the lifting and pushing of the lithium battery. The arrangement adjustment device 5 is installed on both sides of the lifting and pushing device 4. The arrangement adjustment device 5 is used to synchronously adjust the discharge position of the lithium battery. The limiting and blocking device 7 is fixed on the horizontal conveyor 3. The limiting and blocking device 7 is used to block the movement of the lithium battery. The displacement adjustment device 8 is installed on the horizontal conveyor 3. The moving ends of the displacement adjustment device 8 are set on both sides of the horizontal conveyor 3. The interlayer feeding device 6 is installed on the moving end of the displacement adjustment device 8. The interlayer feeding device 6 is used to feed the insulating interlayer 11 to the lithium battery interval.

[0035] In the initial operating state of the device, the horizontal conveyor 3 is connected between the two lithium battery conveyors 21 to form a continuous material conveying channel. The lifting and pushing device 4, the arrangement adjustment device 5, the limit blocking device 7, the displacement adjustment device 8, and the interlayer feeding device 6 are in the initial reset position. The individual lithium batteries to be assembled are conveyed from one side of the lithium battery conveyor 21 to the feeding end of the horizontal conveyor 3. The horizontal conveyor 3 receives the materials and, in conjunction with the moving end of the lifting and pushing device 4, completes the material guiding and conveying, conveying multiple sets of individual lithium batteries to the limit blocking device 7 at the limit blocking position.

[0036] The equipment's identification sensors collect lithium battery position signals in real time and determine the positioning status of multiple lithium battery groups. When all lithium batteries are detected to have reached the preset working position, the control system stops the horizontal conveyor 3, completing the precise positioning of the material. After positioning, the displacement adjustment device 8 is activated, synchronously driving the interlayer feeding device 6 mounted on its movable end to move forward, so that the discharge end of the interlayer feeding device 6 is precisely moved to the working area of ​​the lithium battery group 1; at the same time, the displacement adjustment device 8 pushes the adjustment end of the arrangement adjustment device 5 through the movable end of the lifting and pushing device 4 to contact multiple individual lithium batteries.

[0037] Subsequently, the arrangement and adjustment device 5 initiates synchronous adjustment, driving multiple groups of individual lithium batteries to move at equal intervals, forming uniform insulation assembly gaps between adjacent individual lithium batteries, providing a regular assembly space for the installation of the insulation separator 11. After the gaps are formed, the separator feeding device 6 initiates quantitative feeding, precisely placing the pre-specified insulation separator 11 into the gaps between each lithium battery, completing the automated installation of the insulation structure between lithium batteries and eliminating defects caused by manual placement.

[0038] After the insulating separator 11 is laid out, the arrangement adjustment device 5 reverses and resets, driving each group of individual lithium batteries to move closer together, clamping and pressing the insulating separator 11 to ensure that the insulating separator 11 is tightly attached to the side wall of the lithium battery, meeting the insulation protection process standards of the lithium battery pack 1. Subsequently, the displacement adjustment device 8 reverses and resets, simultaneously driving the separator feeding device 6 and the arrangement adjustment device 5 back to their initial positions, completing the regular arrangement and insulation pretreatment process before winding the lithium battery pack 1.

[0039] After the pretreatment process is completed, the lifting and pushing device 4 starts its lifting action. Its movable end carries the shaped lithium battery pack 1 and rises vertically, accurately pushing the lithium battery pack 1 to the clamping position of the winding fixture 2. After it is in place, the winding fixture 2 starts its clamping and limiting action to rigidly fix the entire lithium battery pack 1, restricting its displacement and shaking, and providing a stable working base for the subsequent insulating tape wrapping operation. Then, the wrapping operation of the winding fixture 2 completes the tape binding and fixing assembly of the lithium battery pack 1.

[0040] After the tape wrapping assembly process of lithium battery pack 1 is completed, the wrapping fixture 2 releases its clamping and limiting state, removing the fixed constraint on lithium battery pack 1; at the same time, the lifting and pushing device 4 drives the lithium battery pack 1 to descend vertically, causing the module to fall back to the conveying end face of the horizontal conveyor 3. Simultaneously, the limiting and blocking device 7 releases its blocking and limiting state, releasing the material conveying authority, and the horizontal conveyor 3 restarts the conveying process, smoothly conveying the assembled lithium battery pack 1 to the input end of the lithium battery conveyor 21 on the other side, completing the automatic unloading of finished materials and process flow, realizing the continuous operation of the entire process of wrapping insulating tape for lithium battery pack 1.

[0041] This device achieves fully automated integration of the entire process of lithium battery pack 1 transfer, orderly arrangement, insulation layer 11 layout, workstation switching, auxiliary winding and finished product unloading through programmed collaborative operation of various functional components. It avoids the operational risks caused by manual intervention, effectively improves the production efficiency and product consistency of lithium battery pack 1 winding processing, and ensures the insulation protection performance of lithium battery pack 1 and the quality of finished product assembly.

[0042] The winding tool 2 is existing technology and will not be described in detail here.

[0043] See Figures 1 to 5 As shown, the lifting and pushing device 4 includes a lifting screw slide 41, a lifting mounting frame 42, and a limiting guide rail 43. The lifting screw slide 41 is vertically installed at the bottom of the horizontal conveyor 3. The lifting mounting frame 42 is slidably installed on both sides of the horizontal conveyor 3, and the lifting mounting frame 42 is connected to the movable end of the lifting screw slide 41. Multiple limiting guide rails 43 are provided and are arranged on both sides of the horizontal conveyor 3. The limiting guide rails 43 are used to limit and guide the movement of the lithium battery, and the bottom of the limiting guide rails 43 is fixedly connected to the lifting mounting frame 42.

[0044] During the lithium battery material conveying stage, the lifting screw slide 41 is in the initial low position, and the limiting guide rail 43 maintains a fixed height adapted to the horizontal conveyor 3. It performs lateral limiting and trajectory guidance on the individual lithium batteries during the conveying process, ensuring that the lithium batteries are fed smoothly along the preset conveying path. It works with the horizontal conveyor 3 to complete the precise positioning of the materials and avoid material conveying deviation and misalignment problems.

[0045] After the lithium batteries have completed the pre-processing steps such as regular arrangement and laying of insulating layers 11, the lifting screw slide 41 starts the vertical lifting drive, which drives the lifting mounting frame 42 to move smoothly upward along both sides of the horizontal conveyor 3. Simultaneously, it drives the limit guide rails 43 on both sides and the lithium battery pack 1 carried on the inner side of the rails to be vertically lifted as a whole, accurately pushing the lithium battery pack 1 to the working position of the upper winding fixture 2, providing a stable working height for subsequent module clamping and fixing and insulating tape winding operations.

[0046] See Figures 3 to 8As shown, the limiting guide rail 43 includes a horizontal adjusting rail 431, an adjusting plate 432, an expansion spring 433, an adjusting screw 434, a limiting stop block 435, and a precision shrinking assembly 436. The horizontal adjusting rail 431 has multiple mounting grooves 4311, and its bottom is fixedly connected to the lifting mounting frame 42. The adjusting plate 432 is vertically mounted on the horizontal adjusting rail 431, and is slidably connected to the mounting grooves 4311. Multiple expansion springs 433 are evenly distributed between the horizontal adjusting rail 431 and the adjusting plate 432. The adjusting screw 434 is rotatably mounted in the mounting groove 4311. The limiting stop block 435 is slidably mounted in the mounting groove 4311, with one side of the limiting stop block 435 abutting against the adjusting plate 432, and the limiting stop block 435 is threadedly connected to the adjusting screw 434. The precision shrinking assembly 436 is mounted on the winding fixture 2 and is used to guide the adjusting plate 432 to shrink and calibrate its movement.

[0047] The bottom of the horizontal adjustment rail 431 is rigidly fixed to the lifting mounting frame 42, providing an installation reference and load-bearing support for the overall adjustable structure. The vertically arranged adjustment plate 432 forms a sliding fit with the horizontal adjustment rail 431 through the mounting groove 4311, constituting the execution structure for lateral contact and guidance of the lithium battery pack 1; multiple sets of evenly distributed expansion springs 433 are assembled between the horizontal adjustment rail 431 and the adjustment plate 432, which can continuously output elastic thrust, so that the adjustment plate 432 is always tightly attached to the limiting block 435, realizing the elastic adaptive fitting and positioning of the adjustment plate 432.

[0048] The adjusting screw 434 is rotatably fitted into the mounting groove 4311 of the horizontal adjusting rail 431, forming a threaded transmission engagement with the slidingly assembled limiting block 435, thus constituting a manual adjustment mechanism for the rail spacing. By rotating the adjusting screw 434, the limiting block 435 can be driven to make linear displacement along the mounting groove 4311. Relying on the limiting action of the limiting block 435 against the adjusting plate 432, the sliding displacement of the adjusting plate 432 is precisely controlled, realizing the adaptive adjustment of the spacing between the two adjusting plates 432. This adapts to the limiting and guiding requirements of single lithium batteries and lithium battery packs 1 of different shapes and sizes, broadening the adaptability of the device to various working conditions.

[0049] In the lithium battery material conveying operation, the lifting screw slide 41 is in the low initial position, the limiting guide rail 43 maintains a fixed working height, and the two side adjustment plates 432 form a limiting constraint from the side of the lithium battery pack 1, which guides the trajectory and corrects the attitude of the individual lithium batteries in the conveying process, effectively avoiding the problems of deviation, misalignment and tilting that occur in the material conveying process, ensuring that multiple groups of individual lithium batteries are fed smoothly along the preset path, and working with the horizontal conveyor 3 to complete the precise positioning of the materials.

[0050] During lithium battery pretreatment and workstation switching, the limiting guide rail 43 moves synchronously with the lifting mounting frame 42. The horizontal adjusting rail 431 bears the load at the bottom of the lithium battery pack 1, and with the lateral limiting constraints of the adjusting plates 432 on both sides, the overall posture of the lithium battery pack 1 is maintained. During the vertical lifting process of the lifting mounting frame 42 driven by the lifting screw slide 41, the limiting guide rail 43 locks the relative position of the lithium battery pack 1 throughout the process, driving the shaped lithium battery pack 1 to be lifted vertically and smoothly, and accurately pushed to the working position of the winding fixture 2.

[0051] Once the lithium battery pack 1 is lifted into position and enters the tape winding operation, the precision shrinkage component 436 mounted on the winding fixture 2 starts operating, applying a precise guiding constraint force to the adjustment plate 432, driving the adjustment plates 432 on both sides to shrink and calibrate slightly, further conforming to the side wall of the lithium battery pack 1, eliminating lateral misalignment and flatness deviation of the lithium battery pack 1, ensuring that the lithium battery pack 1 maintains a regular and flat posture, and preventing defects such as uneven winding and adhesion failure caused by offset and shaking during the tape winding process, thus ensuring the accuracy of the insulating tape winding operation and the quality of the finished product assembly.

[0052] See Figures 1 to 8 As shown, the precision shrinking assembly 436 includes a guide wheel 4361 mounted on one end of the adjusting plate 432, and a guide block 4362 mounted on the winding fixture 2. The guide block 4362 has an inclined guide groove 4363 inside, which is used to guide the guide wheel 4361.

[0053] The guide wheel 4361 of the precision shrinking component 436 is correspondingly assembled at the end of the adjusting plate 432 and can complete the lifting and lowering displacement synchronously with the adjusting plate 432; the guide block 4362 is fixedly installed at the corresponding working position of the winding tool 2, and has an inclined guide groove 4363 inside, which constitutes the guiding limit and trajectory constraint structure of the guide wheel 4361.

[0054] During the lifting and jacking process at the device station switching position, the lifting and jacking device 4 drives the limiting guide rail 43 to rise vertically as a whole. The horizontal adjusting rail 431 supports the aligned lithium battery pack 1 and moves upward synchronously. The adjusting plate 432 rises synchronously with the limiting guide rail 43, causing the guide wheel 4361 at the end of the adjusting plate 432 to gradually approach and contact the inclined guide groove 4363 inside the guide block 4362. As the lithium battery pack 1 continues to be lifted into place, the guide wheel 4361 continues to slide along the inclined trajectory of the inclined guide groove 4363. Through the guiding and pressing action of the inclined surface, a precise horizontal thrust is generated on the guide wheel 4361.

[0055] Under the constraint and guidance of the inclined guide groove 4363, the guide wheel 4361 generates a horizontal fine-tuning displacement, which simultaneously drives the adjustment plate 432 to overcome the elastic tension of the expansion spring 433 to perform a small contraction calibration movement, so that the adjustment plates 432 on both sides are more tightly attached to the side wall of the lithium battery pack 1, eliminating the lateral assembly gap and flatness deviation of the lithium battery pack 1, realizing the secondary precise limit correction of the lithium battery pack 1, and keeping the lithium battery pack 1 as a whole in a flat and regular assembly posture.

[0056] The precision shrinking component 436 uses a mechanical inclined self-adaptive guiding structure to simultaneously complete attitude calibration as the lithium battery pack 1 arrives at the winding station. It does not require an additional independent drive mechanism and can effectively avoid problems such as lithium battery offset, shaking, and irregular bonding during tape winding operations. This ensures the uniformity and bonding accuracy of the insulating tape winding, and improves the overall quality and operational stability of the insulating winding assembly of the lithium battery pack 1.

[0057] See Figures 3 to 9 As shown, the arrangement adjustment device 5 includes a sliding mounting rail 51, a first return spring 52, a movable abutment block 53, and a segmented pushing device 54. Multiple sliding mounting rails 51 are provided and evenly distributed on the side of the adjustment plate 432. The sliding mounting rails 51 are slidably connected to the adjustment plate 432, and the interior of the sliding mounting rails 51 has multiple equally spaced limiting grooves 511. Multiple first return springs 52 are provided and evenly distributed between the sliding mounting rails 51 and the adjustment plate 432. Multiple movable abutment blocks 53 are provided and distributed in the limiting grooves 511. The movable abutment blocks 53 are slidably connected to the sliding mounting rails 51, and the side of the movable abutment block 53 has an elastic anti-slip surface. The segmented pushing device 54 is used to simultaneously push multiple movable abutment blocks 53 along the limiting grooves 511.

[0058] After the equipment completes the precise positioning of the lithium battery materials, the displacement adjustment device 8 starts the feeding operation, and simultaneously pushes the arrangement adjustment device 5 to move towards the lithium battery pack 1. This causes the sliding mounting rail 51 to slide relative to the adjustment plate 432 and compress the first reset spring 52, so that the elastic anti-slip surface of each movable contact block 53 precisely fits the side wall of the corresponding single lithium battery, completing the synchronous contact positioning of multiple lithium batteries and establishing a stable force transmission foundation.

[0059] After the positioning and bonding are completed, the segmented pushing device 54 starts the forward synchronous pushing operation, driving multiple sets of movable contact blocks 53 to make equidistant segmented displacement movements along the limiting groove 511 of the sliding mounting rail 51. Through the rigid pushing action of the movable contact blocks 53, each set of individual lithium batteries is moved synchronously, so that a uniform and regular insulation assembly gap is formed between adjacent individual lithium batteries. This provides a standard assembly space for the precise layout of the subsequent insulation layer 11, completely avoiding defects such as uneven gaps and disordered layout caused by manual arrangement.

[0060] After the insulating separator 11 between each lithium battery is automatically placed and laid out by the separator feeding device 6, the segmented pushing device 54 starts the reverse reset action, drives multiple sets of movable contact blocks 53 to retract synchronously, and drives each group of individual lithium batteries to move closer to each other, so as to uniformly clamp and press the laid insulating separator 11, so that the insulating separator 11 is completely and tightly attached to the side wall of the lithium battery, eliminating assembly gaps and meeting the process standards for insulation protection of lithium battery pack 1.

[0061] After all the pretreatment processes are completed, the displacement adjustment device 8 is reversed and reset, removing the thrust constraint on the sliding mounting rail 51. The first reset spring 52 releases its elastic potential energy, pushing the sliding mounting rail 51 to reset as a whole, and driving the entire set of arrangement adjustment devices 5 back to the initial position. This completes the entire process of regular arrangement and insulation pretreatment of the lithium battery pack 1, providing a regular and stable working base for the subsequent module lifting and tape winding processes, and ensuring the consistency of the assembly quality and insulation performance of the finished lithium battery pack 1.

[0062] See Figures 8 to 12 As shown, the segmented pushing device 54 includes a segmented adjusting rod 541, a second return spring 542, and a synchronous pushing device 543. Multiple segmented adjusting rods 541 are provided and distributed on the sliding mounting rail 51. The segmented adjusting rods 541 are slidably connected to the sliding mounting rail 51. Multiple strip grooves 5411 are evenly distributed on the segmented adjusting rods 541, with the lengths of the multiple strip grooves 5411 increasing in a stepped manner. The strip grooves 5411 are in slidable contact with the movable abutment block 53. The second return spring 542 is installed between the segmented adjusting rods 541 and the sliding mounting rail 51. The synchronous pushing device 543 includes a first linear driver installed at the bottom of the horizontal conveyor 3. A sliding bracket 5431 is installed at the output end of the first linear driver. The sliding bracket 5431 has multiple slots 5432 for engaging one end of the segmented adjusting rod 541.

[0063] After the lithium battery is positioned and the movable contact block 53 is stably attached to the side wall of the lithium battery, the synchronous pushing device 543 starts working. The first linear driver outputs a horizontal driving force, which pulls the sliding bracket 5431 to make a directional displacement. The sliding bracket 5431, through the snap-fit ​​structure between the slot 5432 and the segmented adjusting rod 541, synchronously drives the multi-group segmented adjusting rod 541 to slide as a whole along the sliding mounting rail 51, and compresses the second return spring 542 to accumulate return elastic potential energy.

[0064] During the sliding process, the segmented adjusting rod 541, relying on the stepped length arrangement of the strip grooves 5411 on the rod body, forms a sequential and segmented pushing action on each group of movable contact blocks 53. The strip grooves 5411 with different strokes contact and push against the corresponding movable contact blocks 53 in sequence, so that each group of movable contact blocks 53 slides along the limiting grooves 511 of the sliding mounting rail 51 in a preset order and displacement amount, realizing the step-by-step equidistant movement of multiple groups of single lithium batteries, forming a uniform and assembly-standard-compliant installation gap between adjacent lithium batteries, and providing a regular working space for the automated layout of the insulation layer 11.

[0065] After the insulation layer 11 is installed, the first linear actuator drives the sliding bracket 5431 to reverse and reset, causing the segmented adjusting rod 541 to retract synchronously, releasing the pushing constraint on the movable contact block 53. At the same time, the second reset spring 542 releases its elastic potential energy, assisting the segmented adjusting rod 541 to complete a precise reset, so that each group of movable contact blocks 53 synchronously drives the individual lithium batteries to move towards each other, uniformly clamping and pressing the insulation layer 11, achieving a tight fit between the insulation layer 11 and the side wall of the lithium battery, and meeting the module insulation protection process requirements.

[0066] See Figures 3 to 13 As shown, the interlayer feeding device 6 includes a blocking plate 61 and a limiting feeding device 62. The blocking plate 61 is vertically installed on the movable end of the displacement adjusting device 8. Multiple limiting feeding devices 62 are provided and are evenly distributed on the movable end of the displacement adjusting device 8. Each limiting feeding device 62 includes a storage box 621. The side of the storage box 621 is provided with a discharge port. A stroke sensor is installed inside the discharge port. Multiple conveying rollers 622 are rotatably installed on the inner wall of the storage box 621. The conveying rollers 622 are evenly distributed towards the discharge port. A rotation anti-slip layer is provided on the outer side of the conveying rollers 622. A rotation drive device 623 is provided on the top of the storage box 621. The rotation drive device 623 is used to synchronously drive the multiple conveying rollers 622 to rotate. An elastic pushing device is also provided inside the storage box 621. The elastic pushing device is used to push the internally stored insulating interlayer 11 to move towards the conveying rollers 622.

[0067] The blocking plate 61 is vertically fixed to the movable end of the displacement adjustment device 8 and aligned with the discharge end of the limiting discharge device 62. It is used to limit the end and correct the posture of the output insulating layer 11, prevent the insulating layer 11 from shifting or tilting during the discharge process, and ensure that the insulating layer 11 enters the lithium battery gap flat.

[0068] During the operation of the device, after the lithium battery pack 1 completes the equidistant gap regularization and forming, the displacement adjustment device 8 drives the overall displacement and feeding of the separator feeding device 6, so that the discharge port of each limiting feeding device 62 accurately corresponds to the insulation assembly gap between each lithium battery pack, completing the precise alignment of the feeding station. After the station alignment is completed, the rotary drive device 623 starts working, driving multiple sets of conveying rollers 622 to rotate synchronously. Relying on the friction transmission action of the anti-slip layer on the outside of the roller, the insulating separator 11 attached to the surface of the roller moves directionally towards the discharge port.

[0069] During the feeding process of the insulating layer 11, its end is constrained by the blocking placement plate 61, maintaining a flat posture and accurately entering the gap of the lithium battery. When the stroke sensor detects that a single insulating layer 11 has been completely fed into place, it immediately sends a signal to the control system. The control system controls the rotary drive device 623 to stop operating instantly, terminating the feeding action. This achieves precise feeding of a single sheet and eliminates problems such as multiple sheets being fed together, leakage, or misalignment.

[0070] After the insulating layer 11 is laid out, the displacement adjustment device 8 reverses and resets, driving the layer feeding device 6 back to its initial position. Automated and precise feeding is achieved through mechanical structure coordination and sensor-based closed-loop control, effectively improving the uniformity and standardization of the insulation layout of the lithium battery pack 1, and ensuring the insulation protection performance and finished product assembly quality of the lithium battery pack 1.

[0071] See Figures 9 to 13 As shown, the elastic pushing device includes a movable push plate 6241, a pressing spring 6242, and a synchronous reset device. The movable push plate 6241 is slidably installed inside the storage box 621. The pressing spring 6242 is disposed between the storage box 621 and the movable push plate 6241. The synchronous reset device is installed on the side of the storage box 621 and includes a second linear driver 6243 installed on the side of the storage box 621. The output end of the second linear driver 6243 is provided with a sliding push rod 6244. The sliding push rod 6244 passes through multiple movable push plates 6241 in sequence. The sliding push rod 6244 is slidably connected to the movable push plate 6241. Multiple equally spaced abutting protrusions 6245 are distributed on the outer side of the sliding push rod 6244.

[0072] Under normal feeding operation, the pressure spring 6242 continuously releases its elastic potential energy, applying a directional pushing force to the movable push plate 6241. This drives the movable push plate 6241 to slide along the inside of the storage box 621, ensuring that the movable push plate 6241 always applies a constant pressure to the stacked insulating layers 11, keeping the outermost insulating layer 11 in close contact with the surface of the conveyor roller 622. This structure effectively eliminates the gap between the insulating layer 11 and the conveyor roller 622. Combined with the anti-slip layer on the outside of the conveyor roller 622, it prevents feeding slippage, idling, feeding jams, and multiple sheets being discharged at once. This ensures that the insulating layers 11 are conveyed in an orderly, layer-by-layer, and quantitative manner as the conveyor roller 622 rotates, meeting the precise feeding process requirements for the insulation layout of lithium battery gaps.

[0073] When the insulating layer 11 inside the storage box 621 is depleted and material needs to be replenished, the second linear actuator 6243 starts operating, outputting linear driving force and pushing the sliding push rod 6244 to move in a directional direction. During the displacement of the sliding push rod 6244, the abutting protrusions 6245 arranged at equal intervals on its outer side form rigid abutments with each set of movable push plates 6241 in sequence, simultaneously driving multiple sets of movable push plates 6241 to slide in the opposite direction, compressing the pressure spring 6242 and storing elastic potential energy, so that the movable push plates 6241 are moved away from the material discharge side of the storage box 621 and the structure of the conveying roller 622, forming sufficient material filling space inside the storage box 621. At this time, the operator can stack and replenish the insulating layer 11 material inside the storage box 621.

[0074] After the insulation layer 11 is replenished, the second linear actuator 6243 drives the sliding push rod 6244 to reset, releasing the rigid constraint of the abutment protrusion 6245 on the movable push plate 6241. The pressure spring 6242 releases the stored elastic potential energy and pushes the movable push plate 6241 again to press the insulation layer 11, so that the insulation layer 11 re-fits the conveying roller 622 and automatically returns to the waiting state, so that the subsequent automated feeding process can continue.

[0075] See Figures 1 to 3 As shown, the limiting and blocking device 7 includes a rotary driver 71 and a rotating blocking frame 72; the rotary driver 71 is installed above the horizontal conveyor 3; the rotating blocking frame 72 is installed at the output end of the rotary driver 71 and is used to block the lithium battery.

[0076] During the material feeding and placement stage, the rotary driver 71 drives the rotating barrier 72 to maintain a vertical limiting posture, causing the rotating barrier 72 to block the front end of the conveying path at the preset working position of the lithium battery. When the individual lithium batteries to be assembled are introduced into the horizontal conveyor 3 by the side lithium battery conveyor 21 and fed along the conveying path, the vertical rotating barrier 72 achieves end limiting and blocking, constraining the conveying stroke of the individual lithium batteries. Combined with the position detection function of the identification sensor, multiple sets of individual lithium batteries are accurately stopped at the preset working position, avoiding material overshoot and displacement problems, and providing a precise material positioning benchmark for subsequent shutdown positioning, orderly arrangement and insulation layer 11 laying processes.

[0077] After the insulating tape wrapping assembly process of lithium battery pack 1 is completed, the limiting and blocking device 7 performs a release action. The rotary driver 71 outputs a flipping driving force, causing the rotating blocking frame 72 to flip from a vertical blocking posture to a horizontal storage posture, releasing the end obstruction constraint on lithium battery pack 1 and releasing the material conveying authority. At this time, the finished lithium battery pack 1 can be smoothly conveyed out by the horizontal conveyor 3, smoothly exiting the horizontal conveyor 3 and being introduced into the lithium battery conveyor 21 on the other side, completing the automatic unloading of finished products and the continuous flow of the process, providing working conditions for the loading and processing of the next set of lithium battery packs 1.

[0078] See Figure 2 , Figure 9 and Figure 12 As shown, the displacement adjustment device 8 includes a bidirectional screw slide 81 and a horizontal mounting plate 82; the bidirectional screw slide 81 is fixedly installed below the horizontal conveyor 3; there are two horizontal mounting plates 82, which are distributed on both sides of the horizontal conveyor 3, and one side of the horizontal mounting plate 82 is provided with a pressing surface of the pushing arrangement adjustment device 5, and the horizontal mounting plate 82 is fixedly connected to the movable end of the bidirectional screw slide 81.

[0079] In the initial standby state of the device, the bidirectional screw slide 81 is in the initial reset position, and the horizontal mounting plates 82 on both sides are symmetrically distributed on both sides of the horizontal conveyor 3. The arrangement adjustment device 5 and the interlayer feeding device 6 synchronously maintain the initial standby posture to avoid mechanical interference and provide an unobstructed working space for the lithium battery material to be conveyed and positioned.

[0080] After the horizontal conveyor 3 completes the precise positioning of the lithium battery pack 1 and the material conveying process is terminated, the displacement adjustment device 8 starts the feeding operation. The bidirectional screw slide 81 outputs synchronous drive power, driving the horizontal mounting plates 82 on both sides to move symmetrically inward in the horizontal direction. During the displacement of the horizontal mounting plate 82, its side wall pressing surface rigidly pushes against the arrangement adjustment device 5, driving the arrangement adjustment device 5 to pass through the movable end of the lifting and pushing device 4 and make precise contact with the side wall of each group of individual lithium batteries, completing the contact positioning of the lithium battery pack 1, and establishing the force transmission basis for subsequent equidistant gap adjustment; at the same time, the horizontal mounting plate 82 synchronously drives the overall displacement and feeding of the mounted interlayer feeding device 6, so that the discharge end of the interlayer feeding device 6 is precisely aligned with the gap working area of ​​the lithium battery pack 1.
