Description

Technical Field

[0001] This utility model relates to the field of wire feeding equipment technology, and in particular to an auxiliary device for a wire feeding mechanism and a wire feeding device. Background Technology

[0002] Composite current collector materials, as alternatives to aluminum and copper foils for the positive and negative electrodes of lithium-ion batteries, are widely used in the manufacturing process of lithium-ion batteries. Composite current collectors can improve the energy density of lithium-ion batteries, reduce their weight, and decrease the risk of puncture and fire. Vacuum evaporation coating technology, as the mainstream production method for composite current collector materials, has wide applications in new energy, electronic devices, and other fields. Its core lies in heating, evaporating, and depositing a film of metal materials (such as aluminum wire) using vacuum evaporation equipment. The wire feeding mechanism in vacuum coating is a key component of the evaporation equipment, which needs to ensure the continuous and stable feeding of aluminum wire to the evaporation boat. Its wire feeding accuracy directly determines the coating efficiency, film uniformity, and equipment energy consumption, and is an important link in ensuring production stability and product quality.

[0003] In related technologies, the wire feeding mechanism of vacuum evaporation equipment often adopts a single wire feeding wheel structure, which drives the aluminum wire forward through the friction between the wire feeding wheel and the aluminum wire. For example, some equipment uses a single active wire feeding wheel in conjunction with a guide tube to transport the aluminum wire. Its structure is simple and the cost is low, and it was used to some extent in the early evaporation process.

[0004] However, this single wire feeding mechanism can only drive the aluminum wire and lacks the correction and straightening treatment of the aluminum wire. As a result, after the aluminum wire is output from the wire feeding tube, its movement direction is prone to deviate or shake, which causes the relative position of the aluminum wire and the evaporation boat to be unstable, thus affecting the production stability and product quality. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary device and a wire feeding equipment for a wire feeding mechanism, which can straighten and correct aluminum wires, improve wire feeding stability, and thus ensure production stability and product quality.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An auxiliary device for a wire feeding mechanism is provided, comprising:

[0008] The base provides installation space.

[0009] The first pressure roller is rotatably connected to the mounting space of the base;

[0010] The first wire feeding wheel is rotatably connected to the mounting space of the base via a first rotating shaft. The first pressure wheel is arranged opposite to the first wire feeding wheel, and the first pressure wheel can press against the first wire feeding wheel so that the wire is clamped between the first pressure wheel and the first wire feeding wheel.

[0011] The damping assembly includes a damping element, which is mounted on the base and sleeved on the outside of the first rotating shaft, and can abut against the outer peripheral wall of the first rotating shaft.

[0012] As one possible implementation of the auxiliary device for the above-mentioned wire feeding mechanism, the outer peripheral wall of the first wire feeding wheel is provided with a first wire feeding groove, the first wire feeding groove is used for the wire to pass through, and the first pressure wheel can press the wire in the first wire feeding groove.

[0013] As one possible implementation of the auxiliary device for the above-mentioned wire feeding mechanism, the base includes a body, and a first connecting part and a second connecting part connected to the body. The first connecting part and the second connecting part are spaced apart along a first direction. The first connecting part, the second connecting part and the body enclose an installation space. A first rotating shaft is rotatably connected to the body.

[0014] As one possible implementation of the auxiliary device for the aforementioned wire feeding mechanism, the first connecting part is provided with a wire guide port, which is configured to be aligned with the first wire feeding groove between the first pressure roller and the first wire feeding roller in a preset direction, the preset direction being the wire feeding direction.

[0015] As one possible implementation of the above-mentioned auxiliary device for the wire feeding mechanism, the auxiliary device for the wire feeding mechanism further includes a straightening guide tube, which passes through the second connecting part and extends into the installation space. The wire inlet end of the straightening guide tube is configured to be aligned with the first wire feeding groove between the first pressure roller and the first wire feeding roller in a preset direction.

[0016] As one possible implementation of the above-mentioned auxiliary device for the wire feeding mechanism, the auxiliary device for the wire feeding mechanism further includes a connecting rod, which is rotatably connected to the base via a pin, and the first pressure roller is rotatably connected to the connecting rod via a pressure roller rotation shaft.

[0017] As one possible implementation of the above-mentioned auxiliary device for the wire feeding mechanism, the auxiliary device for the wire feeding mechanism further includes an elastic element, which can apply a force to the connecting rod to press the first pressure roller against the first wire feeding roller.

[0018] As one possible implementation of the above-mentioned auxiliary device for the wire feeding mechanism, the auxiliary device for the wire feeding mechanism further includes a spring rod, which is fixedly connected to the connecting rod. An elastic element is sleeved outside the spring rod, and the two ends of the elastic element are respectively connected to or abut against the two ends of the spring rod.

[0019] As one possible implementation of the auxiliary device for the aforementioned wire feeding mechanism, the damping assembly further includes a damping cover plate, which is fixedly installed on the base and can abut against the damping element.

[0020] A wire feeding device is provided, comprising:

[0021] support;

[0022] The second pressure roller and the second wire feeding roller are arranged opposite to each other and are both rotatably connected to the bracket. The second pressure roller can press against the second wire feeding roller so that the wire is clamped between the second pressure roller and the second wire feeding roller.

[0023] In any of the above technical solutions, the axis of the first feeding wheel and the axis of the second feeding wheel are arranged parallel to each other so that the wire passes between the first pressure wheel and the first feeding wheel and then enters between the second pressure wheel and the second feeding wheel.

[0024] The beneficial effects of this utility model are:

[0025] This utility model provides an auxiliary device and equipment for a wire feeding mechanism. When the aluminum wire passes between the first pressure roller and the first wire feeding roller, the first pressure roller and the first wire feeding roller press against each other, forming a radial constraint on the aluminum wire through the clamping force between them. For aluminum wires that have bent or developed residual stress during storage or transportation, this structure can continuously mechanically correct them during the conveying process, eliminating the lateral deviation tendency of the aluminum wire, ensuring that the aluminum wire maintains a straight trajectory after exiting the wire feeding tube, and avoiding the problem of conveying direction deviation caused by the bending of the aluminum wire, thus providing a basis for precise positioning in the subsequent evaporation boat.

[0026] The damping component in the damping assembly is sleeved on the outside of the first rotating shaft and abuts against its outer peripheral wall. It can suppress sudden changes in the rotational speed of the first wire feeding wheel through frictional damping. When the aluminum wire vibrates due to insufficient rigidity or external disturbances, the damping component can absorb the instantaneous impact energy, reduce the vibration amplitude of the first wire feeding wheel, and keep the aluminum wire conveying speed uniform and stable. At the same time, the stable clamping and damping effect reduces the relative sliding between the aluminum wire and the first pressure wheel and the first wire feeding wheel, avoiding the "jamming-impact" phenomenon of the aluminum wire caused by fluctuations in wire feeding resistance. This ensures that the aluminum wire is conveyed to the evaporation boat with constant tension, effectively solving the problem of unstable wire feeding caused by aluminum wire vibration in traditional single wire feeding wheel mechanisms.

[0027] Through the synergistic effect of straightening and stable conveying, the positional accuracy and movement stability of the aluminum wire when entering the evaporation boat are significantly improved, avoiding problems such as evaporation rate fluctuations and uneven film thickness caused by aluminum wire deviation or shaking, thereby ensuring production stability and product quality.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] like Figure 1-3 As shown, an embodiment of this utility model provides an auxiliary device for a wire feeding mechanism, including a base 10, a first pressure roller 11, a first wire feeding roller 12, and a damping assembly. The base 10 has an installation space. The first pressure roller 11 is rotatably connected to the installation space of the base 10. The first wire feeding roller 12 is rotatably connected to the installation space of the base 10 via a first rotating shaft 13. The first pressure roller 11 and the first wire feeding roller 12 are arranged opposite to each other, and the first pressure roller 11 can press against the first wire feeding roller 12 to clamp the wire between the first pressure roller 11 and the first wire feeding roller 12. The damping assembly includes a damping element 21, which is installed on the base 10 and sleeved on the outside of the first rotating shaft 13, and can abut against the outer peripheral wall of the first rotating shaft 13. Specifically, the damping element 21 is a damping block.

[0039] On the one hand, when the aluminum wire passes between the first pressure roller 11 and the first wire feeding roller 12, the first pressure roller 11 and the first wire feeding roller 12 press against each other, forming a radial constraint on the aluminum wire through the clamping force between them. For aluminum wires that have been bent or have residual stress during storage or transportation, this structure can continuously mechanically correct them during the conveying process, eliminate the lateral deviation tendency of the aluminum wire, ensure that the aluminum wire maintains a straight trajectory after being output from the wire feeding tube 28, avoid the problem of conveying direction deviation caused by the bending of the aluminum wire, and provide a basis for the precise positioning of the aluminum wire into the evaporation boat.

[0040] On the other hand, the damping element 21 in the damping assembly is sleeved on the outside of the first rotating shaft 13 and abuts against its outer peripheral wall. It can suppress sudden changes in the rotational speed of the first wire feeding wheel 12 through frictional damping. When the aluminum wire vibrates due to insufficient rigidity or external disturbances, the damping element 21 can absorb the instantaneous impact energy, reduce the vibration amplitude of the first wire feeding wheel 12, and keep the aluminum wire conveying speed uniform and stable. At the same time, the stable clamping and damping effect reduces the relative sliding between the aluminum wire and the first pressure wheel 11 and the first wire feeding wheel 12, avoids the "jamming-impact" phenomenon of the aluminum wire caused by fluctuations in wire feeding resistance, and ensures that the aluminum wire is conveyed to the evaporation boat with constant tension. This effectively solves the problem of unstable wire feeding caused by aluminum wire vibration in traditional single wire feeding wheel mechanisms.

[0041] Through the synergistic effect of straightening and stable conveying, the positional accuracy and movement stability of the aluminum wire when entering the evaporation boat are significantly improved, avoiding problems such as evaporation rate fluctuations and uneven film thickness caused by aluminum wire deviation or shaking, thereby ensuring production stability and product quality.

[0042] Furthermore, the outer peripheral wall of the first wire feeding wheel 12 is provided with a first wire feeding groove, which is used for the wire to pass through. The first pressure wheel 11 can press the wire in the first wire feeding groove. The groove wall of the first wire feeding groove plays a limiting role for the wire, preventing the wire from sliding laterally during the wire feeding process and ensuring that the wire always maintains a straight motion trajectory output.

[0043] like Figure 2 and Figure 3 As shown, a bearing 14 is fixedly connected to the outer peripheral wall of the first rotating shaft 13, and the bearing 14 is disposed between the damping member 21 and the first rotating shaft 13. Specifically, the bearing 14 is an angular contact bearing, which can simultaneously bear radial load and unidirectional axial load. Through paired installation or pre-tightening design, the axial displacement of the first rotating shaft 13 can be effectively constrained, preventing the first wire feeding wheel 12 from axially moving or swaying.

[0044] Optionally, the first wire feeding groove has a V-shaped cross-section. The two inclined surfaces of the V-shaped groove are in line contact with the wire, increasing static friction under the pressure of the first pressure roller 11, effectively preventing the wire from slipping. In addition, the two inclined surfaces of the V-shaped groove can automatically adapt to wires of different diameters through line contact, allowing for compatibility with various specifications of wires without changing the wire feeding roller, thus improving the versatility of the device.

[0045] Optionally, the inner wall of the first wire feeding groove is provided with anti-slip texture. The anti-slip texture significantly improves static friction by increasing the contact roughness between the wire and the groove wall, effectively preventing the wire from slipping during high-speed feeding or load fluctuations, and reducing the impact on wire straightening.

[0046] Furthermore, the base 10 includes a body, and a first connecting part 101 and a second connecting part 102 connected to the body. The first connecting part 101 and the second connecting part 102 are spaced apart along a first direction. The first connecting part 101, the second connecting part 102 and the body enclose an installation space. The first rotating shaft 13 is rotatably connected to the body.

[0047] The first connecting portion 101 and the second connecting portion 102 are spaced apart along the first direction and enclose the body to form an installation space, providing independent and compact housing areas for the first pressure roller 11, the first wire feeding roller 12, and the damping assembly, ensuring that the components do not interfere with each other during operation and improving space utilization. Specifically, as shown... Figure 1As shown, the first connecting part 101, the second connecting part 102 and the main body form a U-shaped frame structure, which facilitates the positioning, installation and debugging of core components such as the first pressure roller 11, the first wire feeding roller 12 and the damping assembly. At the same time, the first connecting part 101 and the second connecting part 102 also provide installation convenience for the conveying of the wire.

[0048] Furthermore, the first connecting part 101 is provided with a wire guide port 103, which is configured to be aligned with the first wire feeding groove between the first pressure roller 11 and the first wire feeding roller 12 in a preset direction, which is the wire feeding direction.

[0049] By aligning the wire guide port 103 with the first wire feeding groove in a preset direction, pre-guiding is completed before the wire enters between the first pressure roller 11 and the first wire feeding roller 12. This allows for precise positioning of the wire, ensuring that the wire enters the first wire feeding groove at the correct angle. This avoids wire jamming, wear, or deviation in the wire feeding trajectory caused by initial position offset, thereby improving the stability of aluminum wire conveying.

[0050] Furthermore, the auxiliary device for the wire feeding mechanism also includes a straightening guide tube 15, which passes through the second connecting part 102 and extends into the installation space. The wire inlet end of the straightening guide tube 15 is configured to be aligned with the first wire feeding groove between the first pressure roller 11 and the first wire feeding roller 12 in a preset direction.

[0051] The inlet end of the straightening guide tube 15 is aligned with the first wire feeding groove to form a continuous guide channel from the wire feeding area to the outlet, further constraining the wire feeding trajectory and preventing the wire from deviating due to elastic recovery or external vibration after leaving the clamp of the first pressure roller 11 and the first wire feeding roller 12. This ensures that the wire is output in a straight line, reduces the bending of the wire caused by the previous feeding or its own material, ensures the straightness of the output wire, and improves the accuracy of downstream processes.

[0052] Furthermore, the auxiliary device for the wire feeding mechanism also includes a connecting rod 16, which is rotatably connected to the base 10 via a pin 17, and the first pressure roller 11 is rotatably connected to the connecting rod 16 via a pressure roller rotation shaft 18.

[0053] Specifically, the connecting rod 16 is rotatably connected to the body of the base 10 via the pin 17. By manually moving the connecting rod 16 to rotate around the axis of the pin 17, the connecting rod 16 can drive the first pressure roller 11 to rise together, so that the first pressure roller 11 can be disengaged from the first wire feeding roller 12, thereby facilitating the wire threading operation of aluminum wire.

[0054] Furthermore, the auxiliary device for the wire feeding mechanism also includes an elastic element 19, which can apply a force to the connecting rod 16 to press the first pressure roller 11 against the first wire feeding roller 12. Specifically, the elastic element 19 is a compression spring.

[0055] The elastic element 19 continuously applies pressure to the connecting rod 16, so that the first pressure roller 11 can press the aluminum wire into the first wire feeding groove of the first wire feeding roller 12, ensuring that the aluminum wire is always properly pressed during the conveying process and avoiding slippage or loosening.

[0056] By replacing the elastic element 19 with different elastic coefficients or adjusting its pre-compression, it can be quickly adapted to threads of different materials and diameters without the need for complex mechanical adjustment structures, thus improving ease of operation.

[0057] Furthermore, the auxiliary device for the wire feeding mechanism also includes a spring rod 20, which is fixedly connected to the connecting rod 16. An elastic element 19 is sleeved on the spring rod 20, and the two ends of the elastic element 19 are respectively connected to or abut against the two ends of the spring rod 20.

[0058] The elastic element 19 is fixed by the spring rod 20, so that the elastic element 19 exerts downward pressure on the connecting rod 16. At the same time, the spring rod 20 provides axial guidance for the elastic element 19, avoiding force dispersion or jamming caused by lateral displacement of the elastic element 19, ensuring the stability and directionality of the pressure on the connecting rod 16, and thus maintaining the uniformity of the clamping force between the first pressure roller 11 and the first wire feeding roller 12.

[0059] Furthermore, the damping assembly also includes a damping cover plate 22, which is fixedly installed on the base 10 and can abut against the damping element 21.

[0060] Specifically, such as Figure 1 As shown, the damping cover plate 22 is bolted to the body for easy disassembly. By abutting against the damping element 21, the damping cover plate 22 can limit its axial displacement and radial deformation, ensuring that the damping element 21 always maintains uniform contact with the outer peripheral wall of the first rotating shaft 13, avoiding loosening or displacement of the damping element 21 due to vibration or long-term use, thereby maintaining a stable friction damping effect and ensuring the buffering accuracy of the speed fluctuation of the first wire feeding wheel 12.

[0061] Furthermore, the damping assembly also includes an adjusting member 23, which is threadedly connected to the damping cover plate 22 and abuts against the damping member 21. Specifically, the adjusting member 23 is a spring plunger.

[0062] The spring plunger controls the clamping pressure on the damping element 21 by controlling the depth of thread insertion, thereby fine-tuning the friction between the damping element 21 and the first rotating shaft 13, achieving stepless adjustment of the damping force. Compared with a fixed damping structure, the buffering effect can be dynamically optimized according to the wire material (e.g., metal wire requires high damping to suppress slippage, while plastic wire requires low damping to prevent breakage) and the wire feeding speed, improving the adaptability of the device to complex working conditions.

[0063] like Figure 4As shown, an embodiment of this utility model provides a wire feeding device, including a bracket 24, a second pressure roller 25, a second wire feeding roller 26, and the aforementioned auxiliary device for the wire feeding mechanism. The second pressure roller 25 and the second wire feeding roller 26 are arranged opposite to each other and are both rotatably connected to the bracket 24. The second pressure roller 25 can press against the second wire feeding roller 26 so that the wire is clamped between the second pressure roller 25 and the second wire feeding roller 26. The axis of the first wire feeding roller 12 and the axis of the second wire feeding roller 26 are arranged parallel to each other so that the wire passes between the first pressure roller 11 and the first wire feeding roller 12 and then enters between the second pressure roller 25 and the second wire feeding roller 26.

[0064] Specifically, the first wire feeding wheel 12 is a driven wire feeding wheel, and the second wire feeding wheel 26 is a driven wire feeding wheel.

[0065] The aluminum wire first passes between the first pressure roller 11 and the first wire feeding roller 12. After being corrected by the first pressure roller 11 and the first wire feeding roller 12, it enters between the second pressure roller 25 and the second wire feeding roller 26. This ensures that the aluminum wire maintains a straight trajectory after being output from the wire feeding tube 28, and ensures that the aluminum wire does not bend, deform or shake, thus providing a basis for precise positioning when it enters the evaporation boat.

[0066] Furthermore, the outer peripheral wall of the second wire feeding wheel 26 is provided with a second wire feeding groove for the wire to pass through, and the second pressure wheel 25 can press against the second wire feeding wheel 26 so that the second pressure wheel 25 presses against the wire in the second wire feeding groove.

[0067] The first and second wire feeding grooves are aligned along the wire conveying direction, forming a series double-clamping structure. The aluminum wire passes sequentially through the clamping areas of the two sets of pressure rollers and wire feeding rollers, effectively dispersing single-point clamping pressure and preventing deformation of the aluminum wire due to excessive compression at a single point. Simultaneously, double limiting prevents the aluminum wire from shifting during long-distance conveying, improving conveying stability. As the aluminum wire moves forward, the rear driven wire feeding roller, due to its damping effect, forces the aluminum wire into a taut state, thus straightening and correcting it, ensuring production stability and product quality.

[0068] Optionally, the cross-section of the second wire feeding groove is V-shaped.

[0069] Furthermore, the wire feeding device also includes a drive motor 27, the output end of which is connected to the second wire feeding wheel 26 for transmission. The drive motor 27 can drive the second wire feeding wheel 26 to rotate around the axis of the second rotating shaft. Specifically, the output end of the drive motor 27 is connected to the second wire feeding wheel 26 for transmission via a bevel gear set.

[0070] The working process of the wire feeding device provided in this embodiment is as follows:

[0071] Reference Figure 1 and Figure 4After passing through the wire guide port 103, the aluminum wire enters the first wire feeding groove between the first pressure roller 11 and the first wire feeding roller 12. Then, it passes through the straightening guide tube 15 and enters the second wire feeding groove between the second pressure roller 25 and the second wire feeding roller 26. The second wire feeding roller 26 is driven to rotate by the drive motor 27. The second wire feeding roller 26 generates a forward traction force on the aluminum wire, pulling the aluminum wire forward. Under the squeezing action of the second pressure roller 25, the aluminum wire is tightly attached to the second wire feeding roller 26 to avoid slippage. Finally, the aluminum wire passes through the wire feeding tube 28 and is guided to the designated position of the evaporation boat, completing the wire feeding work.

[0072] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
