Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of transfer tray, especially relates to a lithium battery cylindrical roll core transfer tray. BACKGROUND

[0002] The lithium battery industry is one of the industries that develop most rapidly in the modern energy field, and its application range covers multiple fields such as consumer electronics, new energy vehicles, energy storage equipment, etc. With the rapid growth of market demand and continuous innovation of technology, the complexity and precision requirements of lithium battery manufacturing process are also increasing. The production process of cylindrical batteries needs to go through multiple key steps, and the winding process and assembly process are particularly important links. In the winding process, the roll core of the cylindrical battery is precisely manufactured by the winding machine, and then needs to be transferred to the assembly process to complete the packaging and other processing links of the battery core. During this transfer process, the tray serves as a carrier to bear the important functions of transportation and protection of the roll core.

[0003] The traditional tray design has many limitations in actual application, especially in the transportation process of cylindrical roll cores. The tray generally accommodates the roll core by setting multiple independent grooves, thereby realizing the relative fixation of the roll core during transportation. However, due to the vibration of the logistics line and other external factors, the cylindrical roll core is prone to rotate in the groove. The two end faces of the cylindrical roll core are the positive and negative tab areas, which function to lead current and connect other battery components. The full tab face is usually covered by multiple small tabs in a spiral shape to improve the energy density and charge-discharge performance of the battery. However, due to the lack of effective protection measures in the tray structure, the vibration of the logistics line can cause the roll core to rotate freely in the groove. During the rotation process, the tabs on the end face of the roll core are prone to rubbing against the groove wall or other roll cores, causing tab scratches or even spreading. Such damage not only reduces the structural integrity of the roll core, but also directly affects the electrical connection reliability of the subsequent assembly process.

[0004] Therefore, how to limit the rotation of the cylindrical roll core in the transfer tray and avoid the spreading of the full tab face of the cylindrical roll core has become a technical problem to be solved. UTILITY MODEL CONTENTS

[0005] The main purpose of the utility model is to provide a lithium battery cylindrical roll core transfer tray, which aims to limit the rotation of the cylindrical roll core in the transfer tray and avoid the spreading of the full tab face of the cylindrical roll core.

[0007] a tray body provided with at least one receiving cavity for receiving the roll core; and

[0008] A U-shaped limiting piece corresponding to the receiving cavity is connected to the tray body and can be used to lock the winding core in the receiving cavity to limit the rotation of the winding core in the receiving cavity. The lithium battery cylindrical winding core transfer tray can effectively limit the rotation and sliding of the lithium battery cylindrical winding core during the transfer process, avoiding damage caused by vibration or collision. The use of the U-shaped limiting piece improves the efficiency of winding core locking and makes the winding core loading and unloading operation more convenient, simple in structure and easy to implement.

[0009] In an embodiment of the present application, the opposite sides of the receiving cavity are respectively provided with a first sliding groove and a second sliding groove, the first free end of the U-shaped limiting piece is slidingly connected in the first sliding groove, and the second free end of the U-shaped limiting piece is slidingly connected in the second sliding groove. When the winding core is placed in the receiving cavity, the U-shaped limiting piece can be slid above the receiving cavity so that the inner side wall of the U-shaped limiting piece is attached to the outer side wall of the winding core. By providing the first sliding groove and the second sliding groove on the opposite sides of the receiving cavity and slidingly connecting the free end of the U-shaped limiting piece with the sliding groove, the installation and locking efficiency of the limiting piece is effectively improved.

[0032] Specifically, the tray body 20 is the main structure of the lithium battery cylindrical roll core 10 transfer tray. The shape can be designed as a rectangle, a square or other suitable shapes for industrial production and transportation according to requirements. The material of the tray body 20 is a durable material, such as high-strength plastic, composite material or metal, so as to provide good structural strength and durability. At least one receiving cavity 21 is arranged on the surface of the tray body 20, and the receiving cavity 21 is used to accommodate the lithium battery cylindrical roll core 10.

[0033] The receiving cavity 21 is arranged on the surface of the tray body 20. The shape and size of the receiving cavity 21 are accurately designed according to the outer diameter and length of the lithium battery cylindrical roll core 10, so as to ensure that the roll core 10 can be stably placed in the receiving cavity 21. The bottom of the receiving cavity 21 can be provided with a buffer pad or other soft structure, so as to protect the lithium battery cylindrical roll core 10 from being damaged by hard materials during transportation. The number of receiving cavities 21 can be adjusted according to the size and expected capacity of the tray body 20, so as to accommodate a plurality of lithium battery cylindrical roll cores 10.

[0034] The U-shaped limiting piece 30 is a locking piece corresponding to the receiving cavity 21 one by one. The U-shaped limiting piece 30 is detachably or slidably connected to the tray body 20, so as to effectively lock the lithium battery cylindrical roll core 10 inside the receiving cavity 21, thereby avoiding the rotation of the roll core 10 during transfer.

[0035] In operation, first, the lithium battery cylindrical roll core 10 is aligned with the receiving cavities 21 on the tray body 20 one by one, and then the U-shaped limiting piece 30 is moved or fixed to the tray body 20 in sequence, so as to complete the locking operation of the roll core 10. After being transferred to the destination, the U-shaped limiting piece 30 can be removed to take out the lithium battery cylindrical roll core 10.

[0036] By using the above technical scheme, the lithium battery cylindrical roll core 10 transfer tray can effectively limit the rotation and sliding of the lithium battery cylindrical roll core 10 during transfer, and avoid damage caused by vibration or collision. The use of the U-shaped limiting piece 30 improves the locking efficiency of the roll core 10, and makes the loading and unloading operation of the roll core 10 more simple and convenient. The structure is simple and easy to implement.

[0037] In an embodiment of the present application, the opposite sides of the receiving cavity 21 are respectively provided with a first sliding groove and a second sliding groove, the first free end of the U-shaped limiting piece 30 is slidingly connected in the first sliding groove, and the second free end of the U-shaped limiting piece 30 is slidingly connected in the second sliding groove, when the roll core 10 is placed in the receiving cavity 21, the U-shaped limiting piece 30 can be slid to above the receiving cavity 21, so that the inner side wall of the U-shaped limiting piece 30 is attached to the outer side wall of the roll core 10.

[0038] Specifically, the tray body 20 is further designed with a first sliding groove and a second sliding groove. The two sliding grooves are respectively arranged on the opposite sides of the receiving cavity 21, parallel to each other, and the size and position of the sliding grooves are designed according to the free ends of the U-shaped limiting piece 30, so as to ensure that the sliding grooves can smoothly guide the sliding of the U-shaped limiting piece 30. The inner wall surface of the sliding groove is lubricated or embedded with a guide rail to reduce the sliding resistance and improve the sliding stability.

[0039] The first free end and the second free end of the U-shaped limiting piece 30 are respectively slidingly connected in the first sliding groove and the second sliding groove. The U-shaped limiting piece 30 can be guided from the sliding groove to above the receiving cavity 21 by sliding operation, and finally form a locking state of the lithium battery cylindrical roll core 10. The inner side wall of the U-shaped limiting piece 30 is designed according to the curvature of the lithium battery cylindrical roll core 10, and can be tightly attached to the outer side wall of the lithium battery cylindrical roll core 10 when sliding to the final position, thereby limiting the radial and axial movement of the roll core 10.

[0040] The tray body 20 is a bearing structure, which is provided with a receiving cavity 21, a first sliding groove and a second sliding groove are respectively arranged on the two side edges of the receiving cavity 21, and opposite to each other. The U-shaped limiting piece 30 is inserted into the first sliding groove and the second sliding groove through the first free end and the second free end thereof. When the lithium battery cylindrical roll core 10 is placed in the receiving cavity 21, the operator can push the U-shaped limiting piece 30 to make it slide along the sliding groove to above the receiving cavity 21. With the completion of the sliding, the inner side wall of the U-shaped limiting piece 30 will be attached to the outer side wall of the lithium battery cylindrical roll core 10, thereby completing the locking.

[0041] By adopting the above technical scheme, the first sliding groove and the second sliding groove are arranged on the opposite sides of the receiving cavity 21, and the free ends of the U-shaped limiting piece 30 are slidingly connected with the sliding grooves, which effectively improves the installation and locking efficiency of the limiting piece. The U-shaped limiting piece 30 automatically forms attachment to the lithium battery cylindrical roll core 10 through sliding operation, avoiding the need for additional buckles or bolt fixing mode of the traditional limiting piece, and the operation is more convenient, saving the installation time.
