Description

Technical Field

[0001] This invention relates to the field of lithium battery component manufacturing technology, specifically a preheating and shaking device for metal wires. Background Technology

[0002] Battery aluminum foil is one of the essential key materials in lithium-ion batteries and other types of batteries, mainly used as the positive electrode current collector. It not only serves as a carrier for current transmission, but also as a supporting structure for active materials, ensuring that electrochemical reactions can proceed efficiently. Battery aluminum foil is made by refining aluminum raw materials into aluminum plates, which are then rolled into aluminum foil. The battery foil is made by casting and rolling molten aluminum, with titanium wire used to assist in dissolution during the processing of molten aluminum.

[0003] Chinese utility model patent CN220636246U, published on March 22, 2024, discloses a titanium wire preheating device for an aluminum flow channel. The device includes a pair of titanium wire reels arranged horizontally from left to right, a dual-channel titanium wire feeding mechanism, and an aluminum flow channel. A titanium wire preheating assembly is provided between the dual-channel titanium wire feeding mechanism and the aluminum flow channel. This assembly has a pair of titanium wire heating channels, which correspond to the positions of the two output ends of the dual-channel titanium wire feeding mechanism. The preheating assembly includes a pair of front and rear preheating tubes, the inner cavity of which serves as the titanium wire heating channel. The preheating tubes are electrically connected to a heater. This utility model has a simple and reasonable structural design. By setting a titanium wire preheating assembly between the dual-channel titanium wire feeding mechanism and the aluminum flow channel, the titanium wire is preheated before being added to the aluminum flow channel, thereby increasing the temperature of the titanium wire, effectively improving the dissolution of the titanium wire when added to the molten aluminum, and greatly reducing the precipitation of the titanium wire during addition.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the existing titanium wire heating devices can only reduce the precipitation of titanium wire in the aluminum liquid by heating the titanium wire to increase its temperature, but cannot increase the contact area with the aluminum liquid. The position of the titanium wire in the aluminum liquid remains unchanged, and it is impossible to reduce the precipitation of titanium wire to a greater extent. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned technical problems and provide a preheating and shaking device for metal wires.

[0006] To achieve the above objectives, the present invention employs the following technical solutions;

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The preheating and shaking device for metal wire of the present invention includes a fixed base plate; a tubular electric furnace and a limiting plate are provided on the upper surface of the fixed base plate; an avoidance hole is provided on the limiting plate; an adjustment unit is provided on the limiting plate; a reciprocating drive unit is provided on the adjustment unit; a rocker arm is sleeved on the reciprocating drive unit; and a limiting ring is fixedly connected to the end of the rocker arm.

[0008] Furthermore, the adjustment unit includes a double-sided limiting groove; the double-sided limiting groove is symmetrically opened on both sides of the limiting plate; limiting posts are symmetrically inserted into the double-sided limiting groove; a rotating sleeve is sleeved on the limiting post; a plurality of second fasteners are threadedly connected to the rotating sleeve; a cantilever is sleeved on the second fastener; and a reciprocating drive unit is provided on the cantilever.

[0009] Furthermore, the reciprocating drive unit includes a drive motor; the drive motor is fixedly connected to the cantilever; a limit pin is inserted into the rotating shaft of the drive motor; a transmission plate is sleeved on the limit pin; the transmission plate is inserted into a slot; the slot is formed on a rotating circular plate; the rotating circular plate is rotatably connected to a rotating groove; a circumferential limit groove is formed on the rotating circular plate; a positioning pin is formed on the cantilever corresponding to the circumferential limit groove; a fourth fastener is threaded through a hole on the rotating circular plate; the fourth fastener is inserted into one end of the rocker arm.

[0010] The preheating and shaking device for metal wire provided by this invention has the following beneficial effects:

[0011] 1. This invention features a reciprocating drive unit on the adjustment unit, which allows the titanium wire to oscillate back and forth, increasing the contact area with the molten aluminum, thus enhancing the dissolution and dispersion of the aluminum and minimizing the precipitation of the titanium wire, resulting in better performance. A rocker arm is fitted onto the reciprocating drive unit; a limiting ring is fixed to the end of the rocker arm. This limiting ring, fitted onto the surface of the titanium wire, changes the bending deformation amplitude of the titanium wire with the reciprocating motion of the rocker arm. Simultaneously, the contact with the clearance hole acts as a lever fulcrum, amplifying the reciprocating bending deformation amplitude of the titanium wire, increasing its movement distance within the molten aluminum tank, and allowing it to contact more molten aluminum, thereby reducing precipitation.

[0012] 2. In this invention, the drive motor is energized to rotate the transmission plate, the rotating disc, and the fourth fastener, thereby causing the rocker arm, which is movably sleeved on the fourth fastener, to reciprocate. This allows the titanium wire located on the limiting ring to move left and right, thereby increasing the contact area and range with the molten aluminum, resulting in more thorough dissolution and preventing precipitation that could lead to crystallization.

[0019] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] It should be noted that in the embodiments of the present invention, all directional indications (such as up-down-left-right-forward-backward...) are only used to explain the relative positional relationship and movement between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0022] Please see Figure 1-4As shown, a preheating and shaking device for a metal wire includes a fixed base plate 1 that is horizontally or vertically fixed to the surface of another object by a user; a tubular electric furnace 2 and a limiting plate 3 are provided on the upper surface of the fixed base plate 1; the limiting plate 3 has a clearance hole 25, which allows the tubular electric furnace 2 to heat the titanium wire, and the position of the titanium wire is adjusted by passing through the clearance hole 25 to bring it close to the temperature of molten aluminum, thereby reducing the precipitation of the titanium wire; the limiting plate 3 has an adjustment unit that can adjust the swing direction of the titanium wire; the adjustment unit has a reciprocating drive unit that can reciprocate to drive the titanium wire into the molten aluminum. The oscillating motion increases the contact area with the molten aluminum, enhancing the dissolution and dispersion of the aluminum and minimizing titanium wire sedimentation for better results. A rocker arm 22 is fitted onto the reciprocating drive unit. A limiting ring 23 is fixed to the end of the rocker arm 22. By fitting the limiting ring 23 onto the surface of the titanium wire, the reciprocating motion of the rocker arm 22 can change the bending deformation amplitude of the titanium wire. Simultaneously, the contact with the clearance hole 25 acts as a lever fulcrum, amplifying the reciprocating bending deformation amplitude of the titanium wire. This increases the movement distance within the molten aluminum tank, allowing for greater contact with the molten aluminum and thus reducing sedimentation.

[0023] The adjustment unit includes a double-sided limiting groove 4; the double-sided limiting groove 4 is symmetrically opened on both sides of the limiting plate 3; the double-sided limiting groove 4 is symmetrically inserted with limiting posts 8; a rotating sleeve 9 is sleeved on the limiting post 8; a plurality of second fasteners 11 are threadedly connected to the rotating sleeve 9; a cantilever 10 is sleeved on the second fastener 11; a reciprocating drive unit is provided on the cantilever 10. The movement path of the rotating sleeve 9, the cantilever 10 and the reciprocating drive unit is restricted by the limiting post 8, so that the angle can be precisely adjusted around the titanium wire, thereby adapting to aluminum liquid tanks of different shapes.

[0024] The reciprocating drive unit includes a drive motor 13; the drive motor 13 is fixedly connected to the cantilever 10; a limit pin 14 is inserted into the rotating shaft of the drive motor 13; a transmission plate 15 is sleeved on the limit pin 14; the transmission plate 15 is inserted into a slot 16; the slot 16 is formed on a rotating circular plate 17; the rotating circular plate 17 is rotatably connected to a rotating groove 18; a circumferential limiting groove 19 is formed on the rotating circular plate 17; a positioning pin 20 is formed on the cantilever 10 corresponding to the circumferential limiting groove 19; the rotating circular plate 17... The upper opening is threaded with a fourth fastener 21; the fourth fastener 21 is inserted into one end of the rocker arm 22. When the drive motor 13 is energized, it drives the transmission plate 15, the rotating circular plate 17 and the fourth fastener 21 to rotate, thereby driving the rocker arm 22, which is movably sleeved on the fourth fastener 21, to reciprocate. This allows the titanium wire located on the limiting ring 23 to move left and right, thereby increasing the contact area and range with the molten aluminum, making the dissolution more thorough and preventing precipitation that could lead to crystallization.

[0025] The rotating sleeve 9 is connected to the corresponding limit plate 3 by a threaded connection through the opening on the corresponding limit plate 3, so that rotating the third fastener 12 can fix the rotating sleeve 9 on the limit plate 3.

[0026] A limiting plate 27 is fixedly connected to the end of the rocker arm 22; a vertical groove 28 is provided on the limiting plate 27 corresponding to the titanium wire. The limiting plate 27 and the vertical groove 28 are used to drive the displacement of the titanium wire, which makes it easier to install and remove the titanium wire and makes it more convenient to use.

[0027] A plug groove 5 is provided on the limiting plate 3 corresponding to the double-sided limiting groove 4; a first fastener 7 is threadedly connected to the plug groove 5; a plug block 6 is sleeved on the first fastener 7, so that the limiting post 8 will not come out of the double-sided limiting groove 4 and cause disintegration.

[0028] A second contact ring 26 is detachably fixed inside the clearance hole 25; a first contact ring 24 is detachably fixed inside the limiting ring 23. The first contact ring 24 and the second contact ring 26, which are made of heat-resistant ceramic, can reduce the friction with the titanium wire and are not affected by temperature.
