Description

Technical Field

[0001] This utility model relates to a shelf for lithium battery separators. Background Technology

[0002] The separator is an inner component of a lithium battery. In the structure of a lithium battery, the separator is one of the key inner components. The performance of the separator determines the battery's interface structure, internal resistance, etc., and directly affects the battery's capacity, cycle life, and safety performance. A high-performance separator plays an important role in improving the overall performance of the battery. Its main function is to separate the positive and negative electrodes of the battery and prevent the two electrodes from contacting and short-circuiting.

[0003] Currently, in industrial practice, lithium battery separators are typically stored and transported in roll form. However, traditional storage methods have some significant drawbacks. For example, traditional racks are not designed with the actual user experience in mind. When placing separator rolls at high or low levels, operators may need to use ladders or other auxiliary tools to retrieve them, which not only increases labor intensity but also reduces work efficiency. Furthermore, because the separator material is very thin and sensitive, improper handling can easily cause physical damage (such as scratches or indentations), thus affecting its quality and the performance of the final battery product. Therefore, how to make lithium battery separators easy to retrieve and place has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lithium battery separator placement rack that facilitates the removal of the battery separator by rotating the rotating shaft to drive each placement position to move downward and then rotating the baffle downward.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a front column, a rear column, and a placement part located between the front and rear columns. The number of front and rear columns is two, extending left and right. It also includes a motor. The placement part has several placement positions. The placement part includes a conveyor belt for installation at each placement position, a left crossbeam and a right crossbeam located on the left and right sides of each placement position, and a front adjusting sleeve fitted over the front and rear ends of the front column and a rear adjusting sleeve fitted over the front and rear ends of the rear column. The front and rear adjusting sleeves are slidably installed on the corresponding front and rear columns and fixed by bolts. Limit seats and limiting plates are provided on the left and right sides of each placement position on the conveyor belt. Each limiting plate is rotatably installed on the conveyor belt. Rotary shafts are installed on the front and rear sides of the conveyor belt, and each rotating shaft is rotatably installed between the left and right crossbeams. The motor is fixedly connected to the rotating shafts.

[0006] The present invention is further configured such that: each of the front adjusting sleeves has a guide block on its inner wall, each of the front columns has a first guide rail for the guide block to slide on, and each of the rear adjusting sleeves has the same shape and size as the front adjusting sleeves and each of the rear columns has a second guide rail.

[0007] The present invention is further configured such that: each of the front pillars has a plurality of first screw holes spaced apart along the vertical direction corresponding to the front adjusting sleeve; the front adjusting sleeve has a first insertion hole corresponding to the first screw holes; each of the rear pillars has a plurality of second screw holes corresponding to the rear adjusting sleeve; and the rear adjusting sleeve has a second insertion hole.

[0008] The present invention is further configured such that the conveyor belt is inclined from top to bottom and from back to front.

[0009] The present invention is further configured such that: each of the conveyor belts is provided with a placement groove on the rotation trajectory of each limiting plate, and the front side of the limiting plate is detachably connected to the conveyor belt.

[0010] The present invention is further configured such that: a first magnet is fixedly installed on the front side of the limiting plate, and a second magnet that attracts the first magnet is provided in each placement slot of the conveyor belt.

[0011] The present invention is further configured to include: a cover plate located at the top of each front column and the top of each rear column, wherein the inner wall of the cover plate is provided with a connecting block made of a material that is prone to deformation, and each connecting block is provided with a limiting slot recessed inward, and the front column is provided with a connecting slot corresponding to the connecting block, and the front column is provided with a limiting block with the limiting slot inserted in the connecting slot.

[0012] The present invention is further configured to include a front reinforcing rod located between adjacent front columns, a rear reinforcing rod located between adjacent rear columns, and a connecting rod located between the front and rear columns.

[0013] By adopting the above technical solution, 1. Therefore, the required diaphragm rolls are placed above the conveyor belt. When it is necessary to remove the diaphragm rolls above the conveyor belt, the motor is started to drive the conveyor belt to move forward, causing the placement position at the front of the conveyor belt to move forward in front of the operator. By rotating the limiting plate downwards, the diaphragm rolls between the two limiting seats behind the limiting plate can be removed. When it is necessary to remove the diaphragm rolls in the row behind the row of limiting plates, the motor continues to drive the synchronous belt to move, causing the row of limiting seats and limiting plates behind the row of limiting plates to face forward in front of the user. By rotating the limiting plate of the row downwards, the diaphragm rolls between the limiting seats can be removed. Since the limiting seats and limiting plates above the conveyor belt can move forward continuously, it is possible to remove each diaphragm roll from the placement rack. 1. Providing convenience, and when there is no need to remove the diaphragm roll, since the limiting plate is located between the two limiting seats and is detachably connected to each limiting seat, the diaphragm roll located between the two limiting seats will not fall out between the two limiting seats and the limiting plate without external force; 2. Since the front adjusting sleeve is located at the front and rear ends of the front column and the rear adjusting sleeve is located at the front and rear ends of the rear column, after the connection and fixation between the front adjusting sleeve, the rear adjusting sleeve and the corresponding front column and rear column are released, the height of the placement part can be changed by changing the height position of the front adjusting sleeve and the rear adjusting sleeve on the corresponding front column and rear column. The position of the front adjusting sleeve and the rear adjusting sleeve can be adjusted by changing the height at which the diaphragm roll is placed, and then the front adjusting sleeve and the rear adjusting sleeve can be fixed to the corresponding front column and rear column by bolts, so as to meet the different height requirements of the user.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-7As shown, this utility model discloses a lithium battery separator placement rack, including a separator roll (not shown in the figure) formed by the lithium battery separator being placed in a roll, a front column 2, a rear column 3, and a placement part 4 located between the front column 2 and the rear column 3. The number of front columns 2 and rear columns 3 are two, extending left and right. The lithium battery separators to be stored are placed on the placement part 4 for storage. At this time, each lithium battery separator placement position 41 is raised due to the front column 2 and the rear column 3, thus avoiding friction damage to the ground. The rack also includes a motor 5. The placement part 4 is provided with several placement positions 41. The placement part 4 includes a conveyor belt 42 for mounting each placement position 41, a left crossbeam 43 and a right crossbeam 44 located on the left and right sides of the placement position 41, and a front adjusting sleeve 431 fitted onto the front column at both ends and a rear adjusting sleeve 441 fitted onto the rear column at both ends. Sleeve 431 and rear adjusting sleeve 441 are slidably installed on the corresponding front column 2 and rear column 3 and fixed by bolts (not shown in the figure). The conveyor belt 42 is provided on both the left and right sides of each placement position 41, and a limiting plate 422 is provided between each conveyor belt 421. Each limiting plate 422 is rotatably installed on the conveyor belt 42. Rotating shafts 425 are inserted and installed on both the front and rear sides of the conveyor belt 42. Each rotating shaft 425 is rotatably installed between the left crossbeam 43 and the right crossbeam 44. The motor 5 is fixedly connected to the rotating shaft 425. Since each placement position 41 is located on the conveyor belt 42 and the conveyor belt 42 is provided on both the left and right sides of each placement position 41, and the limiting plate 422 is rotatably installed between each conveyor belt 421, the left and right sides of the limiting plate 422 are detachably connected to the corresponding conveyor belt 421.Therefore, the required diaphragm roll is placed above the conveyor belt 42. When it is necessary to remove the diaphragm roll located above the conveyor belt 42, the motor 5 is started to drive the conveyor belt 42 to move, causing the placement position 41 at the front of the conveyor belt 42 to move forward in front of the operator. By rotating the limiting plate 422 downwards, the diaphragm roll located between the two conveyor belts 421 behind the limiting plate 422 can be removed. When it is necessary to remove the diaphragm roll located in the row behind the limiting plate 422, the diaphragm roll can be removed. When the membrane roll is removed, the synchronous belt driven by the drive motor 5 continues to move, causing the row of conveyor belts 421 and the limiting plates 422 behind the row of limiting plates 422 to face forward and be in front of the user. The limiting plates 422 then rotate downwards, allowing the membrane rolls located between the conveyor belts 421 to be removed. Because the portion of the conveyor belts 421 and the limiting plates 422 above the conveyor belts 42 can continuously move forward, it facilitates the removal of each membrane roll from the shelf. When there is no need to remove them... When the diaphragm roll is in operation, since the limiting plate 422 is located between the two conveyor belts 421 and is detachably connected to each conveyor belt 421, the diaphragm roll located between the two conveyor belts 421 will not fall out between the two conveyor belts 421 and the limiting plate 422 without external force. 2. Since the front adjusting sleeve 431 is located at both ends of the front column and the rear adjusting sleeve 441 is located at both ends of the rear column, after releasing the connection and fixation between the front adjusting sleeve 431, the rear adjusting sleeve 441 and the corresponding front column 2 and rear column 3, the height of the placement part 4 can be changed by changing the height position of the front adjusting sleeve 431 and the rear adjusting sleeve 441 on the corresponding front column 2 and rear column 3. The position of the front adjusting sleeve 431 and the rear adjusting sleeve 441 can be adjusted by changing the desired placement height of the diaphragm roll, and then the front adjusting sleeve 431 and the rear adjusting sleeve 441 can be fixed to the corresponding front column 2 and rear column 3 by bolts, thus meeting the different height requirements of the user.

[0032] It is worth noting that the placement part 4 in this technical solution can be one or multiple depending on the appropriate spacing of the placement parts 4. The attached figure shows that the placement part 4 is designed as two.

[0033] Each of the front adjusting sleeves 431 has a guide block 4311 on its inner wall, and each of the front uprights 2 has a first guide rail 21 for sliding the guide block 4311. Each of the rear adjusting sleeves 441 has the same shape and size as the front adjusting sleeve 431, and each of the rear uprights 3 has a second guide rail 31. Since both the front adjusting sleeves 431 and the rear adjusting sleeves 441 have guide blocks 4311 on their inner walls, the front adjusting sleeves 431 and the rear adjusting sleeves 441 slide up and down along their corresponding front uprights 2 and rear uprights 3. During the process, the guide block 4311 inside the front adjusting sleeve 431 can move up and down along the first guide rail 21 on the front column 2. Similarly, the guide block 4311 on the rear adjusting sleeve 441 can move up and down along the second guide rail 31. Therefore, the setting of the guide block 4311 can allow the front adjusting sleeve 431 and the rear adjusting sleeve 441 to slide along the first guide rail 21 and the second guide rail 31 on the corresponding front column 2 and rear column 3, thus guiding the adjustment of the front adjusting sleeve 431 and the rear adjusting sleeve 441.

[0034] Each of the front pillars 2 has a plurality of first screw holes 22 spaced vertically on the front adjusting sleeve 431, and the front adjusting sleeve 431 has a first insertion hole 4312 corresponding to the first screw holes 22. Each of the rear pillars 3 has a plurality of second screw holes 32 on the rear adjusting sleeve 441, and the rear adjusting sleeve 441 has a second insertion hole 4411. Therefore, when determining the height of the placement part 4, each front adjusting sleeve 431 is placed at the corresponding height of the front pillar 2. At this time, the bolts (not shown in the figure) are inserted into the first insertion holes 4312 on the front adjusting sleeve 431 to fix the placement part 4 at the required height on the front pillar 2. The screw hole 22 is threaded. Similarly, each rear adjustment sleeve 441 is placed at the corresponding height of the rear column 3, so that the bolt is inserted into the second insertion hole 4411 on the rear adjustment sleeve 441 and threaded into the second screw hole 32 on the rear column 3 where the required placement part 4 is fixed at the height. This determines the height position of the placement part 4 on the front column 2 and the rear column 3. When it is necessary to change the position of the placement part 4, the bolts between the front column 2 and the front adjustment sleeve 431 and the bolts between the rear column 3 and the rear adjustment sleeve 441 are unscrewed to change the height of the placement part 4. The bolts are then inserted to determine the position of the placement part 4.

[0035] Preferably, the conveyor belt 42 is inclined from top to bottom and from back to front. Since the conveyor belt 42 is inclined from top to bottom and from back to front, after the position of the placement part 4 is determined between the front column 2 and the rear column 3, each placement position 41 moves forward continuously as the rotating shaft 425 is rotated by the rotation of the motor 5. After the downward rotation of the limiting plate 422, the diaphragm roll can fall along the inclined direction of the conveyor belt 42 under the action of gravity, thereby realizing the picking and placing of the diaphragm roll. Therefore, the inclined conveyor belt 42 can facilitate the removal of the diaphragm roll.

[0036] The conveyor belt 42 is provided with placement slots 423 on the rotation trajectory of each limiting plate 422. The front side of the limiting plate 422 is detachably connected to the conveyor belt 42. Due to the existence of each placement slot 423, after the limiting plate 422 is separated from the fixed connection with the adjacent conveyor belt 421, rotating the limiting plate 422 downwards can remove the diaphragm located on the placement position 41. At the same time, the limiting plate 422 can fall downwards into the placement slot 423 and connect with the conveyor belt 42. This allows the limiting plate 422 to be stably located in the corresponding placement slot 423 without the action of external force. When the limiting plate 422 does not need to limit the diaphragm roll located in the placement position 41, it can be positioned downwards in the synchronous belt, ensuring the flatness and aesthetics of the synchronous belt.

[0037] Preferably, a first magnet 4221 is fixedly installed on the front side of the limiting plate 422, and a second magnet 424 that attracts the first magnet 4221 is provided in each placement slot 423 of the conveyor belt 42. Since the limiting plate 422 can fall into the corresponding placement slot 423 after the connection and fixation between the limiting plate 422 and the conveyor belts 421 on both sides is released, the limiting plate 422 can fall into the corresponding placement slot 423 when rotated downwards. At this time, the first magnet 4221 on the front side of the limiting plate 422 can attract the second magnet 424 located in the corresponding placement slot 423 of the conveyor belt 42, so that the limiting plate 422 will not rotate arbitrarily without the action of external force.

[0038] In addition, it includes cover plates 6 located at the top of each front column 2 and the top of each rear column 3. The inner wall of the cover plate 6 is provided with connecting blocks 61 made of a material that is easily deformable, such as rubber. Each connecting block 61 is provided with a limiting slot 611 recessed inward. The front column 2 is provided with a connecting slot 23 corresponding to the connecting block 61. The front column 2 is provided with a limiting block 24 for inserting the limiting slot 611 in the connecting slot 23. Since the cover plate 6 is located at the top of the front column 2 and the rear column 3, the presence of the cover plate 6 allows the left crossbeam 43 and the right crossbeam 44 to move upward during the height adjustment of the placement part 4 without passing over the cover plate 6. Thus, the cover plate 6 can provide a limit for the height adjustment path of the left crossbeam 43 and the right crossbeam 44. The cover plate 6 has a connecting plug 61 inside. When the cover plate 6 is installed on the top of the front column 2 and the rear column 3, the cover plate 6 will be subjected to an outward deformation force, which will enable the connecting plug 61 to align with the corresponding connecting slot 23. When the connecting plug 61 enters the corresponding connecting slot 23, the part of the connecting plug 61 located inside the limiting slot 611 will first enter the connecting slot 23 and then forcefully pass over the corresponding limiting plug 24 to achieve the cooperation between the limiting plug 24 and the limiting slot 611. Similarly, when the cover plate 6 needs to be removed from the top of the front column 2 and the rear column 3, the limiting slot 611 can limit the separation of the plug 24, thereby allowing the cover plate 6 to be removed from the top of the front column 2 and the rear column 3.

[0039] In addition, it also includes a front reinforcing rod 7 located between adjacent front columns 2, a rear reinforcing rod 8 located between adjacent rear columns 3, and a connecting rod 1 located between the front columns 2 and the rear columns 3. Since the front reinforcing rod 7 is located between adjacent front columns 2 and the rear reinforcing rod 8 is located between adjacent rear columns 3, and there is also a connecting rod 1 between the front columns 2 and the rear columns 3, the strength between the front columns and the rear columns that play a supporting role can be effectively improved.

[0040] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
