The present invention relates to a battery electrode supply system.

A battery manufacturing process consists of an electrode manufacturing process, a cell manufacturing process, and a pack manufacturing process in order.

In detail, the electrode manufacturing process is made in the order of a firing process, a mixing process, a coating process, a roll pressing process, and a slitting process.

In detail, the firing process refers to a step of preparing a cathode active material by putting a raw material including a compound and a transition metal compound in a sagger, which is a firing container, and firing it in a specific temperature range according to the type of the raw material.

The mixing process refers to a step of adding and mixing a conductive agent and a binder to the active material.

The coating process refers to a step of applying a slurry in which an active material, a conductive agent, and a binder are evenly mixed on a material.

The pressing process refers to a step of compressing the material so that the active material adheres well.

The slitting process refers to a step of adjusting the size of an electrode for a battery assembly process.

In addition, the pack manufacturing process includes a module and a pack process surrounding the cell after the degas process has been completed.

The present invention relates to a system for spreading and supplying an electrode film provided in a roll form in a notching and drying process and a lamination and stacking process of the cell manufacturing process.

Specifically, it relates to a battery electrode supply system that automatically connects the start of a new electrode roll (standby electrode roll) supplied through a distribution conveyor and the end of an exhausted electrode roll (used electrode lock).

Figure 1 is a plan view of a conventional battery electrode supply system, Figure 2 is a front view of the conventional battery electrode supply system.

1 and 2, the conventional battery electrode supply system (1) used in the notching and drying process and the lamination and stacking process is a material warehouse through an Automated Guided Vehicle (AGV) (V). The material is transported from the to the distribution conveyor (2).

Here, the material means an electrode or an electrode film wound in a roll shape after passing through a slitting process. A state in which an electrode or an electrode film is wound in a roll shape is defined as an electrode bobbin 6 . The bobbin is transferred to the distribution conveyor (2) by the unmanned transport vehicle (V) in a state placed on a skid (skid). The distribution conveyor 2 is provided with a negative electrode roll conveyor 2a on which the negative electrode material is transported, and a positive electrode roll conveyor 2b on which the positive electrode material is transported, respectively.

And, the hoist 5 is provided on the upper side of the distribution conveyor to be able to move vertically and horizontally. Then, the hoist 5 grabs the electrode bobbin 6 supplied to the distribution conveyor 2 and transfers it to the chucking unit 3 .

Then, the bobbin shuttle 4 in the electrode supply unit moves to the chucking unit 3 and is located directly below the hoist 5 holding the electrode bobbin 6 .

Then, the hoist 5 lowers the electrode bobbin 6 held by it and lowers it to the bobbin shuttle 4, and the bobbin shuttle 4 chucks the electrode bobbin 6 and then returns to the electrode supply unit. .

The bobbin shuttle 4 returned to the electrode supply unit rotates 90 degrees about the vertical axis, and the operator removes the tape attached to the end of the electrode wound on the electrode bobbin 6, unwinds the electrode and attaches it to the suction plate.

The bobbin shuttle 4 includes an electrode support part 4a that rotatably holds the electrode bobbin 6 , and an adsorption part 4b that sucks the end of the electrode released from the electrode bobbin 6 .

Also, in the bobbin shuttle 4, a bobbin shuttle 4A for a standby electrode and a bobbin shuttle 4B for a use electrode are disposed adjacent to each other. In addition, the adsorption part and the cutting part are used to connect the end of the standby electrode and the end of the used electrode.

In detail, in the state where the end of the used electrode is cut at the adsorption part of the used electrode and adsorbed, and the end of the standby electrode is adsorbed at the adsorption part of the standby electrode, the adsorption part of the use electrode and the adsorption part of the standby electrode are in close contact with the standby electrode The start part and the end part of the electrode used are connected.

On the other hand, the suction part of the bobbin shuttle 4 for standby electrodes returned to the electrode supply unit by chucking the standby electrode bobbin 6 from the hoist 5 faces the suction part of the bobbin shuttle for use electrodes. In this state, it is difficult for the operator to manually release the electrode of the standby electrode bobbin 6 and make it adsorbed to the adsorption unit.

For this reason, in order for the operator to remove the tape attached to the electrode start part of the standby electrode bobbin 6 and to untie the electrode start part to facilitate adsorption to the adsorption part, the bobbin shuttle 4 for the standby electrode is rotate 90 degrees

When the start portion of the standby electrode and the end portion of the used electrode are connected at the adsorption part, the film-shaped electrode wound on the standby electrode bobbin 6 is unwound and a notching and drying process or a lamination and stacking process is performed.

In the case of the conventional battery electrode supply system described above, there is a limitation in the process in which the process of releasing the start portion of the electrode bobbin from the bobbin shuttle for the standby electrode and adsorbing the electrode bobbin to the adsorption unit is manually performed by an operator.

As a result, a deviation occurs in the electrode connection portion according to the work skill of the operator, and a deviation occurs in the work time, thereby causing a problem in that productivity is lowered.

In addition, there is a disadvantage in that the maintainability of the hoist is lowered due to the height of the hoist 5 for transporting the standby electrode.

The present invention is proposed to improve the above problems.

A battery electrode supply system according to an embodiment of the present invention for achieving the above object includes an electrode bobbin in which an electrode having a predetermined width is wound in a roll form, and a skid rotatably supporting the electrode bobbin Logistics conveyors that take over material sets; an input shuttle capable of receiving the set of materials from the distribution conveyor and rotating the set of materials to a first angle for alignment of electrode tabs; a main conveyor that receives the set of materials from the input shuttle; an electrode supply unit that receives the set of materials from the main conveyor and rotates the set of materials at a second angle in a state in which electrode supply is possible; and an electrode connection unit connecting the use electrode and the standby electrode of the material set.

In addition, the skid is mounted on a base frame, a support shaft extending upward from the base frame, a bobbin shaft support portion provided on an upper end of the support shaft to support the shaft of the electrode bobbin, and the base frame, the It may include a pair of clamping units each holding the left and right ends of the electrode wound on the electrode bobbin.

According to the battery electrode supply system according to the embodiment of the present invention having the configuration as described above, there are the following effects.

First, since the start of the electrode of the standby electrode bobbin is released and supplied in a state fixed to the clamp of the skid, the process of manually removing the tape attached to the end of the electrode by the operator is omitted.

Second, there is an advantage that the gripping unit holds the end of the electrode fixed to the clamp, releases the roll, and transfers the roll to the adsorption unit automatically.

Third, since the vertical axis feeder provided to the adsorption unit takes over the end of the electrode transferred by the gripping unit and raises it to the adsorption unit, there is an advantage that no operator intervention is required.

In this way, since the connection between the standby electrode and the used electrode is automatically made, productivity can be improved and the electrode connection deviation can be minimized.

Fourth, since the electrode bobbin is coupled to the skid without using a hoist and transferred from the distribution conveyor to the electrode supply unit, there is an advantage in that the hoist maintenance problem is solved.

7 is a perspective view of a material set showing a process in which the gripping unit takes over the end of the electrode held by the clamping unit;

Referring to FIG. 7 , the gripping unit 40 includes a gripper bed 41 and a gripper 42 , wherein the gripper 42 includes a pair of electrode grip parts 421 in the form of tongs; The cam follower 422 may include a function of moving the electrode grip portion 421 in a vertical direction and a function of rotating the electrode grip portion 421 .

The electrode grip part 421 performs the same function as that of the clamp 252 , that is, a function of gripping an end of an electrode constituting the electrode bobbin 30 .

First, the set of materials is transferred to the electrode supply unit 14 , and the phase is changed to a state in which the rotation axis of the electrode bobbin 30 is perpendicular to the gripper bed 41 by the turning table 141 .

In this state, the gripper 42 moves to the lower side of the electrode bobbin 30 along the gripper bed 41 and stops immediately below the electrode end held in a vertical state by the clamping unit 25 . do.

Then, the electrode grip portion 421 is rotated in the first direction (the direction in which the clamp portion faces the end of the electrode), preparing to grip the end of the electrode.

In a state in which the electrode grip part 421 is ready to grip the end of the electrode, the cam follower 422 rises while passing between the pair of clamp guides 253 .

On the other hand, the cam follower 422 is designed to have a width wider than the separation distance between the pair of clamp guides 253, and as the cam follower 422 rises, the pair of clamp guides facing each other ( 253) moves horizontally in the direction away from each other and opens. As a result, the pair of clamps 252 in the contact state are also separated, and the state holding the end of the electrode, that is, the clamping state is released.

In addition, the reason that the electrode grip part 421 further rises upward while holding the end of the electrode is to prevent the electrode from interfering with the clamping unit 25 when it is released and transferred to the electrode connection part 15 . can be understood as a purpose.

Meanwhile, the electrode grip part 421 transferred to the electrode connection part 15 rotates in a second direction opposite to the first direction so that an end of the electrode faces the sky.

In this state, the electrode is raised to the first adsorption and cutting part 60 by a vertical axis feeder 50 constituting the electrode connection part 15 .

The first adsorption and cutting unit 60 may include an adsorption unit forming a vertical surface and a cutting unit cutting the electrode adsorbed to the adsorption unit.

In detail, a slit extending horizontally to at least a length greater than the width of the electrode is formed at a point between the upper end and the lower end of the adsorption unit, and the cutter constituting the cutting unit reciprocates along the slit.

According to this configuration, the electrode raised by the vertical axis feeder 50 is adsorbed to the adsorption unit. In a state in which the electrode is adsorbed to the adsorption unit, the cutter moves along the slit to cut the electrode. For this, the end of the electrode will have to be vertically transported to at least a point higher than the slit.

When the electrode is cut by the cutting unit, the electrode is maintained in a state in which the electrode is adsorbed on the suction surface corresponding to the space between the slit and the lower end of the suction unit.

At the same time, the electrode end of the bobbin used is adsorbed to the adsorption part of the second adsorption and cutting unit 70 , and the electrode is separated from the wick of the electrode bobbin by the cutter moving along the slit. In addition, the cut end of the used electrode is maintained in a state of being adsorbed to the adsorption surface of the second adsorption and cutting unit 70 .

The adsorption surface of the first adsorption and cutting unit 60 and the adsorption surface of the second adsorption and cutting unit 70 face each other. Then, the second adsorption and cutting unit 70 moves horizontally to the first adsorption and cutting unit 60 so that the two adsorption surfaces are brought into close contact, and heat is applied to the adsorption surface.

As a result, the standby electrode adsorbed on the adsorption surface of the first adsorption and cutting unit 60 and the use electrode adsorbed on the adsorption surface of the second adsorption and cutting unit 70 are connected to each other. Then, as the electrode bobbin 30 is unwound, the standby electrode connected to the end of the used electrode is transferred to a notch line or a lamination line along the web guide.

In a state in which the electrode grip portion 421 of the gripping unit 40 is positioned directly below the lifting arm 54 , the electrode grip portion 421 rotates in the second direction so that the end of the electrode faces the sky make it become

In this state, the lifting arm 54 descends, and the electrode grip portion 55 grabs and takes over the end of the electrode. And, the electrode grip portion 421 is opened so that the state of gripping the electrode is released. Then, the lifting arm 54 rises at least to the upper end of the first adsorption and cutting unit 60 .

And, when one surface of the electrode is in close contact with the adsorption surface of the first adsorption and cutting unit 60 , the adsorption pump operates so that the electrode is strongly adsorbed to the adsorption surface of the first adsorption and cutting unit 60 . do. In a state in which the electrode is adsorbed to the adsorption surface, the cutter moves along the slit to cut the tip of the electrode, and the electrode piece held by the electrode grip portion 55 is disposed of.

According to the battery electrode supply system 10 according to the present invention as described above, the end of the electrode wound on the electrode bobbin in the material set state is clamped in the clamping unit 25 while maintaining the state clamped by the electrode supply unit 14. Since it is transported, there is an advantage in that the operator does not have to work to remove the tape attached to the end of the electrode.

In addition, the gripping unit 40 automatically moves to the vertical axis feeder 50 to automatically transfer the electrode of the standby electrode bobbin to the electrode grip portion 55 of the vertical axis feeder 50, and the vertical axis feeder 50 Since the electrode is automatically adsorbed to the first adsorption and cutting unit 60 by the above, there is an advantage that the electrode adsorption process, which has been manually performed by an operator in the past, is no longer required.
