Technical Field
[0001] This utility model belongs to the field of aluminum-nickel strip technology, specifically relating to an aluminum-nickel strip with an anti-loosening mechanism. Background Technology
[0002] Aluminum-nickel strip is a metal strip with an aluminum base and a nickel plating layer on the surface. Typically, an electroplating process is used to form a nickel layer only a few micrometers thick on the aluminum strip surface to improve the aluminum's corrosion resistance and solderability. Its structure combines a physical plating layer with the aluminum substrate. Its mechanical strength is similar to pure aluminum strip, and its electrical conductivity is slightly improved compared to pure aluminum. However, its overall performance is more limited compared to aluminum-nickel composite strip, and it is mostly used in applications where performance requirements are not high, such as connecting ordinary electronic components and low-end battery tabs.
[0003] In modern industrial production, aluminum-nickel strip is typically packaged and stored in rolls. This packaging and storage method has profound industry background and practical needs. As a crucial basic material in electronics, batteries, and new energy fields, aluminum-nickel strip is often used in applications requiring continuous and automated processing. For example, in lithium battery tab manufacturing and solar cell welding, rolled aluminum-nickel strip can seamlessly integrate with automated production equipment, efficiently producing finished products through processes such as rolling, cutting, and welding, significantly improving production efficiency. Furthermore, aluminum-nickel strip is thin and flexible; rolling not only avoids quality problems such as deformation and scratches caused by folding and compression during transportation and storage, but also significantly saves storage space, facilitating standardized management and large-scale procurement for enterprises. From an industry development perspective, with the miniaturization of electronic devices and the advancement of high-energy-density battery technology, the demand for aluminum-nickel strip continues to grow, making rolled packaging a key link in ensuring the efficient operation of the supply chain.
[0004] Currently, aluminum-nickel strips are mostly stored by winding them up with cores after processing for convenient transportation. However, aluminum-nickel strips are typically thin (micrometers to millimeters) and soft, making them prone to loosening due to their own elasticity or external vibrations when coiled. Once loosened, the strip may wrinkle, become tangled, or have its edges curl up, which not only damages the flatness and dimensional accuracy of the material but also affects the positioning accuracy during subsequent processing (such as stamping and cutting), and may even lead to equipment jamming and processing failure. Utility Model Content
[0005] The purpose of this invention is to provide an aluminum-nickel strip with an anti-loosening mechanism, aiming to solve the problem that existing aluminum-nickel strips are mostly wound up and stored using cores after processing for convenient transportation and use. However, aluminum-nickel strips are usually thin (micrometers to millimeters) and soft in texture, making them prone to loosening due to their own elasticity or external vibrations when wound. Once loosened, the strip may wrinkle, become entangled, or have its edges curl up, which not only damages the flatness and dimensional accuracy of the material but also affects the positioning accuracy during subsequent processing (such as stamping, cutting, etc.), and may even lead to problems such as equipment jamming and processing failure.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum-nickel strip with an anti-loosening mechanism, comprising an aluminum-nickel strip roll, the surface of which abuts against a rubber pad on the bottom surface of a lower pressure plate, connectors connected to both ends of the lower pressure plate, the connectors having circular grooves that fit onto a screw surface, the screw surface being threadedly connected to a threaded head, the bottom surface of the threaded head abutting against the top of the connector, the bottom surface of the screw being connected to a groove on a limiting sleeve surface, a limiting block connected to the inner wall surface of the limiting sleeve, the limiting block being slidably connected to a groove on the surface of a take-up core, two sets of slots equally spaced on the surface of the take-up core, the slots engaging with a limiting groove on the surface of an insert rod, the insert rod being inserted into a fixing groove on the surface of the limiting sleeve, and the limiting sleeve surface abutting against the surface of the aluminum-nickel strip roll.
[0007] As a preferred embodiment of the present invention, an aluminum-nickel strip with an anti-loosening mechanism, wherein the connector, the circular groove, the screw, and the threaded head constitute a threaded connection structure.
[0008] As a preferred embodiment of the present invention, an aluminum-nickel strip with an anti-loosening mechanism is provided, wherein a circular groove is provided on the top surface of the limiting sleeve near the aluminum-nickel strip roll, and the shape and size of the groove are adapted to the screw.
[0009] As a preferred embodiment of the present invention, an aluminum-nickel strip with an anti-loosening mechanism, two sets of sliding grooves are symmetrically distributed on both sides of the surface of the winding core. The sliding grooves are "T"-shaped grooves, and their shape and size are adapted to the limiting block.
[0010] As a preferred embodiment of the present invention, an aluminum-nickel strip with an anti-loosening mechanism is provided, wherein a set of limiting grooves are symmetrically opened on one end surface of the insertion rod, and the shape and size of the limiting grooves are adapted to the semi-circular rubber protrusions on the surface of the slot.
[0011] As a preferred embodiment of the present invention, an aluminum-nickel strip with an anti-loosening mechanism is provided, wherein a set of circular fixing grooves are respectively opened on the surface of the limiting sleeve, and the shape and size of the fixing grooves are adapted to the insertion rod.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] By cooperating with the aluminum-nickel strip coil, the pressure plate, the connector, the circular groove, the screw, the threaded head, and the limiting sleeve, the position of the threaded head connected to the screw is adjusted according to the thickness of the aluminum-nickel strip coil wound on the winding core. The threaded head then presses down on the connector, causing the pressure plate to press down and fix the wound aluminum-nickel strip coil, thus preventing it from becoming loose on the winding core. This would prevent wrinkles and curling during temporary storage and transportation, which would affect subsequent use.
[0014] Meanwhile, the mutual cooperation between the limiting block, winding core, slide groove, slot, insertion rod, limiting groove and fixing groove allows the position of the limiting sleeves on both sides to be adjusted according to the width of the wound aluminum-nickel strip, thereby facilitating the clamping and fixing of multiple models of aluminum-nickel strip and preventing them from loosening or slipping off from the side.

[0022] 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.
[0023] Please see Figures 1-5 The present invention provides the following technical solution: an aluminum-nickel strip with an anti-loosening mechanism, comprising an aluminum-nickel strip roll 1, the surface of the aluminum-nickel strip roll 1 abutting against a rubber pad on the bottom surface of a lower pressure plate 2, connecting heads 3 connected to both ends of the lower pressure plate 2, a circular groove 4 on the surface of the connecting head 3 being sleeved onto the surface of a screw 5, a threaded head 6 being threadedly connected to the surface of the screw 5, the bottom surface of the threaded head 6 abutting against the top of the connecting head 3, the bottom surface of the screw 5 being connected to a groove on the surface of a limiting sleeve 7, a limiting block 8 being connected to the inner wall surface of the limiting sleeve 7, a sliding groove 10 on the surface of a winding core 9 being slidably connected to the surface of the limiting block 8, two sets of slots 11 being equally spaced on the surface of the winding core 9, the surface of the slots 11 being engaged with a limiting groove 13 on the surface of an insert rod 12, the surface of the insert rod 12 being inserted into a fixing groove 14 on the surface of the limiting sleeve 7, and the surface of the limiting sleeve 7 abutting against the surface of the aluminum-nickel strip roll 1.
[0024] Preferably, the connector 3, the circular groove 4, the screw 5, and the threaded head 6 form a threaded connection structure.
[0025] In practical use, after the winding is completed, select the appropriate size of the lower pressure plate 2 and put the connectors 3 connected at both ends onto the screw 5. At this time, the rubber pads glued to the bottom of the lower pressure plate 2 abut against the top of the aluminum-nickel strip roll 1. While using the threaded head 6 to connect to the screw 5, tighten it downwards until the threaded head 6 abuts against the top of the connector 3.
[0026] Preferably, the top surface of the limiting sleeve 7 near the aluminum-nickel strip coil 1 has a circular groove, and the shape and size of the groove are adapted to the screw 5.
[0027] In practical use, the groove on the top of the limiting sleeve 7 is used to connect the screw 5. After the aluminum-nickel strip 1 is wound up, the screw 5 connected to the limiting sleeves on both sides and the rotatable and adjustable threaded head 6 are used to press down the lower pressure plate 2, so that the wound aluminum-nickel strip 1 can be fixed in the winding position to avoid loosening during storage and affecting the storage quality.
[0028] Preferably, two sets of sliding grooves 10 are symmetrically distributed on both sides of the surface of the winding core 9. The sliding grooves 10 are "T"-shaped grooves, and their shape and size are adapted to the limiting block 8.
[0029] In practical use, depending on the width of the aluminum-nickel strip roll 1 to be wound, the two sets of limiting sleeves 7 that slide on the winding core 9 are slid onto the groove 10, thereby adjusting the distance between the two sets of limiting sleeves 7 so that they abut against both sides of the aluminum-nickel strip roll 1, preventing the aluminum-nickel strip roll 1 from tilting to the side.
[0030] Preferably, a set of limiting grooves 13 are symmetrically formed on one end surface of the insertion rod 12, and the shape and size of the limiting grooves 13 are adapted to the semi-circular rubber protrusions on the surface of the slot 11.
[0031] In practical use, the limiting groove 13 on the surface of the insert rod 12 engages with the circular rubber block on the surface of the slot 11, thereby fixing its connection on the surface of the take-up core 9, and thus fixing the position of the limiting sleeve 7 on the surface of the take-up core 9.
[0032] Preferably, a set of circular fixing grooves 14 are respectively opened on the surface of the limiting sleeve 7, and the shape and size of the fixing grooves 14 are adapted to the insertion rod 12.
[0033] In practical use, the fixing grooves 14 on both sides of the limiting sleeve 7 are used to allow the insertion rod 12 to be inserted into the fixing groove 14 and then inserted into the slot 11, thereby fixing the position of the limiting sleeve 7 on the surface of the take-up core 9. At the same time, the annular rubber ring bonded to the surface of the insertion rod 12 can increase the friction at the intersection of it with the limiting sleeve 7 and the take-up core 9, thereby fixing the connection stability of the insertion rod 12 within the limiting sleeve 7 and the take-up core 9.
[0034] Working principle: During the production and processing of aluminum-nickel strip coil 1, a take-up core 9 is used to wind and store it. A take-up core 9 and limiting sleeves 7 of the appropriate size are selected according to the model of the aluminum-nickel strip coil 1 being processed. Based on the required width of the aluminum-nickel strip coil 1, the two sets of limiting sleeves 7 sliding on the take-up core 9 are slid onto the slide groove 10, thereby adjusting the distance between the two sets of limiting sleeves 7. After adjustment, according to the adjusted position of the limiting sleeves 7, the insertion rod 12 is inserted into the fixing groove 14 and locked in the slot 11, fixing the position of the limiting sleeves 7 on the take-up core 9. Simultaneously, the two sets of slots 11, evenly spaced on the surface of the take-up core 9, meet the dimensions of most aluminum-nickel strip coils 1 currently required for production. Therefore, based on the required size of the aluminum-nickel strip coil 1 being wound and stored, the insertion rod 12 is inserted into the slot 11, thereby... The produced aluminum-nickel strip coil 1 is wound with equal tension. After winding, a lower pressure plate 2 of appropriate size is selected, and the connectors 3 connected at both ends are respectively sleeved on the screw 5. At this time, the rubber pads glued to the bottom of the lower pressure plate 2 abut against the top of the aluminum-nickel strip coil 1. While using the threaded head 6 to connect to the screw 5, it is tightened downwards until the threaded head 6 abuts against the top of the connector 3. In this design, the threaded surfaces of the screw 5 and the threaded head 6 are selected to be zinc-plated, nickel-plated, or coated with Dacromet coating according to the actual use. This can prevent rust and improve the stability of the friction coefficient, reducing loosening caused by corrosion or wear. Thus, the lower pressure plate 2 abuts against the surface of the aluminum-nickel strip coil 1 to make it stably wound on the surface of the winding core 9, avoiding wrinkles and curling caused by looseness on the surface of the winding core 9, which would affect the quality of subsequent production and use.
[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
