Abstract

PROBLEM TO BE SOLVED: To easily stick a tape on both surfaces of a plate material, and prevent the generation of positional displacement of the tape by sticking a tape piece on one surface of a plate material, and thereafter, bending the tape piece at an end of the plate material, and folding up this bent tape piece to the other surface of the plate material for sticking. SOLUTION: An adhesive tape piece 3 is stuck on a top surface as one surface of a plate-shaped projecting part 2. When the projecting part 2 contacts with a fixed roller 26, the carrying operation of a carrying device for carrying the plate material 1 is temporarily stopped. A turn-up roller 18 is raised and moved close to the fixed roller 26, and simultaneously, a turn-up core part 22c is turned so as to be latched with the tape piece 3 projected from the projecting part 2. Furthermore, turn of a claw lever 22 is hindered and stopped when the claw lever 22 is displaced downward in relation to the projecting part 2. The fixed roller 26 abuts on the top surface of the projecting part 2 through the tape 3, and the roller 18 abuts on the lower surface of the projecting part 2 through the tape 3. After the roller 18 is moved from one side end of the projecting part 2 to the other side end thereof, the tape is stuck on the lower surface of the projecting part 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, both surfaces of a plate-like body, which are necessary when manufacturing a lithium secondary battery, and
Or, it relates to a tape sticking device for sticking tapes at one time.

[0002]

2. Description of the Related Art For example, in order to manufacture a lithium secondary battery, a projection is formed on a part of a plate-like body which constitutes an electrode, and a conductive adhesive is formed on both surfaces of the projection. You have to stick the tape.

In addition, in order to improve productivity, it is required to feed the plate-shaped body at a high speed, feed the adhesive tape at a high speed in accordance with this, cut it, and attach it to both sides of the projection of the plate-shaped body. It

FIG. 10 shows an example of a conventional tape sticking means. That is, the adhesive tape pieces c, c cut into a required area on both surfaces of the protrusion b of the plate-shaped body A are opposed to each other. The adhesive tape pieces c, c are adhesive surfaces with an adhesive applied to the surface facing the plate-shaped body protrusion b.

Adhesive tape pieces c, c are pressed against both sides of the projection b by appropriate means to attach the adhesive tape to the plate-like body A. However, this adhesive tape is unrolled from the wound reel and is cut into a predetermined area after holding the end and becomes a piece, but the tape itself has some elasticity and there is variation in the cut area. Is likely to occur.
When two pieces of adhesive tape pieces c, c having different areas are attached, naturally, the opposite sides are displaced.

Even if two very accurately cut tape pieces are obtained, the adhesive tape pieces c, c on both sides are obtained.
It is necessary to have extremely high precision in accurately sticking the four sides of the sheet and sticking them together, and usually, as shown in FIG. 11, a deviation easily occurs in the XY directions.

In any case, the adhesive applied to the mating surface of the adhesive tape piece is exposed. A plate like this,
If the secondary battery constituent member is used as it is, a conductive material or a chemical reaction agent adheres to the exposed adhesive surface, which may cause performance deterioration.

As another conventional means, FIG.
There is a tape sticking device as shown in 2. As shown in FIG. 3A, a pair of reels e, e around which an adhesive tape d is wound are pivotally supported so as to face each other.
Delivered via.

The tip portion of each adhesive tape is attached to both sides of the tip portion of the plate-like body D which is on standby by an appropriate means. As shown in FIG. 3B, the plate-shaped body D is conveyed, and a pair of pressing rollers g, g are pivotally supported in the conveying direction and guided between these rollers. The plate-like body D is conveyed with the adhesive tapes d and d adhered on both sides of the tip,
Moreover, since both sides of the pressing roller g are clamped by the pressing rollers g, g,
The adhesive tape is surely pressed down on the plate-like body and stuck. (In the figure, the portion where the plate-shaped body and the adhesive tape are attached is drawn with a gap. The same applies hereinafter.) As shown in FIG. 7C, the adhesive tapes d and d are attached to both sides of the plate-shaped body D. When attached, the cutting mechanism k operates to cut the adhesive tape.
Then, the next plate-shaped body D is conveyed to a predetermined position and stands by until the end portions of the adhesive tapes d and d are attached to both surfaces of the front end portion.

Even with such a device, the adhesive tapes d and d can be attached to both surfaces of the plate-like body D at the same time.
Due to its configuration, the plate-like body must be conveyed in a straight line without fail. Therefore, even if it is used in an index device, for example, it is not possible to attach the tape at a high speed and it is necessary to reduce the productivity.

Further, the accuracy of sticking the adhesive tape d to the plate-like body D is easily influenced by the accuracy of the plate-like body being conveyed and the meandering of the adhesive tape being fed out, and the speed is high and stable. It is impossible to obtain positioning accuracy.

[0012]

As a conventional tape adhering means described above, as shown in FIG.
In the example in which the adhesive tape pieces c, c are adhered to both sides of the plate-like protrusion b at the same time, the tape itself has some elasticity,
The cut area is likely to vary. If two pieces of adhesive tape pieces having different areas are stuck together, naturally the sides do not exactly overlap each other.

Even if two very accurately cut tape pieces are obtained, adhesive tape pieces c, c on both sides are obtained.
It is necessary to have extremely high precision in accurately sticking the four sides of the sheet and sticking them together, and usually, as shown in FIG. 11, a deviation easily occurs in the XY directions.

In a device as shown in FIG. 12 in which the adhesive tapes d, d are sequentially adhered from one end to the other end of the plate-like body D, the plate-like body D is surely conveyed linearly. Even if it is used in the index device, high-speed tape attachment is impossible, and it is necessary to reduce productivity.

The accuracy of sticking the adhesive tape d to the plate-like body D is easily influenced by the accuracy of conveying the plate-like body and the meandering of the adhesive tape being fed out, and the speed is high and stable. It is impossible to obtain positioning accuracy.

Next, as shown in FIG. 3B, this bent tape piece 3 is folded back toward the back surface of the plate-shaped projecting portion 2. Then, the tape piece 3 is attached to the back surface which is the other surface of the protrusion 2.

In the end, the tape pieces 3 are attached to both sides of the plate-like projection 2, and since the same tape piece is folded back, the tape pieces on both sides do not have a large deviation at each side position, The exposure of the adhesive surface can be prevented.

Next, a specific tape sticking device for realizing such a tape sticking means will be described. FIG.
As shown in FIGS. 3 (A) and 3 (B) and FIGS. 3 (A) and 3 (B), reference numeral 10 in the drawing denotes a base which is vertically erected here, and a support tool is provided on a side surface of the base. A slide unit 12 is supported via 11 so as to be reciprocally movable in the horizontal direction.

On one side of this slide unit 12,
A cam rod 13 connected to a reciprocating drive source (not shown) is provided to reciprocally drive the slide unit with respect to the base 10.

The slide unit 12 includes a moving body 1
4 are provided integrally. A center portion of a swing lever 15 is pivotally supported on the moving body 14 via a fulcrum pin 16, and both ends of the lever are swingable vertically in a seesaw shape.

A control roller 17 is rotatably supported on the front side surface at the left end of the swing lever 15 in the drawing.
At the right end, the folding roller 18 is rotatably supported on the opposite side surface. The upper end of the tension spring 19 is hooked on the end of the swing lever 15 near the control roller 17.

The lower end portion of the tension spring 19 is hooked on the side portion of the fixed cam 20 provided on the base 10. That is, the control roller 17 elastically rolls on the cam surface, which is the upper end surface of the fixed cam 20, by the elastic force of the tension spring 19.

The cam surface of the fixed cam 20 extends along the longitudinal direction of the rocking lever 15 and has the same height from the right end portion to the vicinity of the left end portion, and only the left end portion is one step higher. It is formed.

When the moving body 14 moves, the rocking lever 15 provided there also moves together, and the tension spring 19 is moved.
The control roller 17 rolls on the cam surface of the fixed cam 20 under the influence of the elastic force of.

A kick bolt 21 is projected from the left end surface of the moving body 14. A side portion of a claw lever body 22, which will be described later, elastically contacts the head portion of the kick bolt 21. That is, the pawl lever body 22 has the vertical piece 22.
a and a horizontal piece 22b integrally provided at the upper end of the vertical piece.

The vertical piece 22a is pivotally supported on a predetermined portion of the base 10 by a pivot bolt 23. Therefore, the pawl lever body 22 is entirely swingable. A tension spring 24 is stretched between the upper end of the base 10 and the horizontal piece 22b of the pawl lever body 22 so that the rocking body can be rotated clockwise with the pivot support bolt 23 as a fulcrum. It is elastically biased.

The kick bolt 21 is positioned in the direction of rotation of the vertical piece 22a of the pawl lever body 22, and its rotation is restricted by contacting the head. Therefore, if the movable body 14 moves, the kick bolt 21 integrated with the movable body 14 moves, and the pawl lever body 22 rotates due to the elastic force of the tension spring 24.

A stopper bolt 25 is provided on one side of the base 10 so that the side of the vertical piece 22a comes into contact with the movable body when the pawl lever 22 is rotated by a predetermined angle. Regardless of the movement of 14, the further rotation is restricted.

c. A fixed roller 26 is rotatably supported on the upper surface of the base 10 at a position close to the tip of the bent claw portion 22c.

A tape sticking apparatus constructed in this way is shown in FIG. 4 and FIGS. 4 (A) to 4 (D).
The operation of attaching the adhesive tape piece 3 to both surfaces of the projection 2 of the plate-shaped body 1 will be described in order.

The carrying device 27 carries the plate-shaped body 1 integrally provided with the protrusion 2. An adhesive tape piece 3 is attached to the upper surface, which is one surface of the plate-like protrusion 2. That is, only half of the tape piece 3 in the longitudinal direction is attached to the protrusion 2, and the other half protrudes from the protrusion 2 along the moving direction of the slide unit 12.

When the protrusion 2 rolls against the fixed roller 26 via the tape piece 3, the conveying operation of the conveying device 27 with respect to the plate-shaped body 1 is temporarily stopped. In this state, the tip of the bent claw portion 22c formed on the claw lever body 22 with respect to the fixed roller 26 is above the fixed roller 26, and the control roller 17 is an upper stage formed on the left side of the fixed cam 20. It is on the cam surface, and the folding roller 18 is located below the plate 1 and on the left side of the fixed roller 26.

At this timing, the cam rod 13
Is pulled to the right in FIG. 3 (A). The slide unit 12 is biased to slide in the same direction, and the moving body 14 integrated with the slide unit 12 slides in the same direction.

Swing lever 1 provided on the moving body 14
5 also moves in the same direction. Due to the elastic force of the tension spring 19, the control roller 17 moves down from the upper cam surface of the fixed cam 20 to the lower cam surface.

The swing lever 15 rotates by the difference between the upper and lower cam surfaces of the fixed cam 20. That is, as the control roller 17 is lowered, the folding roller 18 is raised and the lever 15 is rotated counterclockwise.

At the same time, the kick bolt 25 moves together with the moving body 14, and the action of the tension spring 24 causes the pawl lever body 2 to move.
2 follows and rotates. The claw lever body 22 is the pivot bolt 2
It rotates clockwise about 3 as a fulcrum, and this horizontal piece 2
2b is inclined.

As shown in FIG. 4 (B), the position of the folding roller 18 rises and moves to the vicinity of the fixed roller 26 as the moving body 14 moves. At the same time, the bent claw portion 22c rotates in the clockwise direction and hooks on the portion of the tape piece 3 protruding from the protrusion 2. When the rotation further continues and is displaced to a position below the protrusion 2, the claw lever body 22
Is stopped by the stopper bolt 25 from rotating and stops.

The tape piece 3 is bent along the side edge of the projection 2 by about 90 ° with respect to the projection surface. As shown in FIG. 6C, the folding roller 18 continues to move, passes through the tip of the bending claw portion 22c at a high position, and comes into contact with the vertically bent tape piece 3. Finally, the folding roller 18 rolls on the lower surface which is the other surface of the protrusion 2, and the tape piece 3 is interposed between the roller 18 and the protrusion 2.

That is, the fixed roller 26 contacts the upper surface of the protrusion 2 via the tape piece 3, and the folding roller 18 contacts the lower surface of the protrusion 2 via the tape piece 3. When the folding roller 18 moves from one side end of the protrusion 2 to the other side end, the tape is attached to the entire lower surface of the protrusion 2. As a result, the tape pieces 3 are formed on both sides of the protrusion 2.
Will be attached.

The folding roller 18 moves a distance L as shown in FIG. This time, cam rod 1
3 moves back. The slide unit 12, the moving body 14, and the swing lever 15 move integrally in the opposite direction.

As shown in FIG. 4D, the folding roller 18 presses the tape piece 3 against the lower surface of the protrusion 2 immediately after the backward movement,
Make more reliable attachment. Then, the control roller 17 is placed on the upper cam surface of the fixed cam 20, and the folding roller 17 is lowered in position by that amount.

The kick bolt 21 presses the claw lever body 22 to return it to the original posture. The tip of the bending claw 22c rises and waits for the next plate-shaped body 1 to be conveyed. Hereinafter, the operation described above is repeated.

The tape sticking device of the second invention as shown in FIG. 5 may be used. As shown in FIG. 3A, the adhesive tape piece 3 </ b> A is attached to the surface of the plate-shaped protrusion 2 and is conveyed. At this time, the tape piece 3A is attached so as to have a longitudinal dimension that is at least twice the width dimension of the protrusion 2 as in the case described above, but here, from the protrusion 2 to the transport direction side. Must stand out.

An air nozzle 30 which blows high-pressure air toward the lower projection in the carrying direction of the projection 2.
And a fixed base 3 whose upper end surface is located slightly below the protrusion.
1 and a push-in cylinder 32, which is a pressing body, are arranged facing the upper portion.

As shown in FIG. 3B, when the tape piece 3A portion protruding from the plate-shaped projecting portion 2 reaches the lower portion of the air nozzle 30, it receives high pressure air blown from the air nozzle.

Since this tape piece 3A is not supported at all, it can be easily bent by high pressure air. However, the tape piece 3 already attached to the protrusion 2
Since the protrusion supports the tape piece at the portion A, there is no bending here. Eventually, the tape piece 3A is bent along the side edge of the protrusion 2 by about 90 °.

As shown in FIG. 6C, the protrusion 2 is continuously conveyed, and the bent tape piece 3A comes into contact with the side edge of the fixed base 31. Since the protrusion 2 is still conveyed, the bent tape piece 3A is interposed between the upper surface of the fixed base 31 and the protrusion 2. That is, the tape piece 3A is folded back along the lower surface of the protrusion 2, and as a result, the tape piece is attached to both front and back surfaces of the protrusion.

Then, with the protrusion 2 completely placed on the upper surface of the fixed base 31, this conveyance is temporarily stopped. The push-in cylinder 32 operates at a timing, and the fixed base 31
The upper protrusion 2 and the tape piece 3A are pressed. Therefore,
The tape pieces 3A are surely attached to both surfaces of the protrusion 2.

As shown in FIG. 6, the strip-shaped adhesive tapes 3B, 3 are formed on a part of both sides of the plate 1A and across the width direction.
There is a request to attach B. The tape sticking device of the third invention satisfies this requirement.

7 to 9 show examples of specific structures of the above apparatus. That is, the adhesive tape 3B having one surface coated with the adhesive is wound around the supply reels 40A and 40B. The supply reels 40A and 40B are provided as a pair in a state of being separated and opposed to each other in the vertical direction.

The intermediate reels 41a and 41b are pivotally supported at positions adjacent to the respective supply reels 40A and 40B. The intermediate reel 41a adjacent to the upper supply reel 40A is located above the supply reels. To do. On the other hand, the intermediate reel 41 adjacent to the lower supply reel 40B
b is located on the lower side of this supply reel.

The adhesive tape 3B is extended from each of the supply reels 40A and 40B so as to be hooked on the adjacent intermediate reels 41a and 41b. Where the upper supply reel 4
The adhesive tape 3B fed from 0A is set so that the adhesive surface faces upward and the non-adhesive surface rolls on the intermediate reel 41a. The adhesive surface of the adhesive tape 3B drawn from the lower supply reel 40B faces downward, and the intermediate reel 41
It is set so that the non-adhesive surface is brought into contact with b.

In the tape feeding direction through the respective intermediate reels 41a and 41b, a polygonal body 42 which will be described later is formed.
A and 42B are provided. The polygons 42A, 42B
Are provided so as to be spaced apart and face each other in the vertical direction, and have the same structure as each other. That is, here, it is formed of a regular hexagonal thin box body, and the rotary shaft 43 is provided at the central portion on one surface side, and is mechanically connected to a drive source (not shown).

The drive source is adapted to intermittently rotate the polygonal bodies 42A and 42B by an angle equal to the number of polygons. That is, since the polygonal bodies 42A and 42B have a regular hexagonal shape, they are intermittently rotated by 360 ° / 6 = 60 °.

Moreover, the polygon bodies 42A and 42B of each other are
Always has a stop position so that one side of each side faces in parallel with each other. In particular, as shown only in FIG. 8, a plurality of air holes 45 ... Are provided in each side face 44 of the polygonal bodies 42A and 42B, and an air guide hole 46 is provided in the rotary shaft 43. .

A hose (not shown) communicating with a vacuum pump, which is a vacuum source, is connected to the base end of the rotary shaft 43, and the insides of the polygonal bodies 42A and 42B are always in a negative pressure state. There is.

The tape 3B extending to the polygons 42A and 42B is adsorbed and held by the side portion 44 in the negative pressure state through the air holes 45, and the state does not change even when the polygons rotate.

Slots 47 are provided along the apex portions of the polygonal bodies 42A and 42B. The width dimension of the long hole 47 is sufficiently wider than the width dimension of the tape 3B.

Further, in a state where the polygonal bodies 42A and 42B are stopped, the cutting mechanism 4 is placed at a position facing only a predetermined apex angle portion.
8 are arranged. In FIG. 9, only one cutting mechanism is shown.
The cutting mechanism 48 includes a cutter 49 and a solenoid 50 that drives the cutter to project and retract with respect to a polygonal body.

When the solenoid 50 drives the cutter 49 to project, the tip of the cutter 49 has polygonal bodies 42A, 4A.
It inserts in the long hole 47 formed in the apex part of 2B. Here, the tape 3B that is adsorbed over the two side portions 44, 44 of the polygonal bodies 42A, 42B is cut by the cutter 49.

At least the polygonal bodies 42A, 42B and their rotary drive sources are supported by a lifting mechanism (not shown). The elevating mechanism is to elevate and lower in a direction in which the polygonal bodies come into contact with and separate from each other at a timing while the rotation of the polygonal bodies is stopped.

In the tape sticking apparatus configured as described above, the tapes 3B and 3B wound around the pair of supply reels 40A and 40B are respectively extended, and the intermediate reel 4

The adhesive surface of each tape 3B is the front surface side, and the non-adhesive surface closely contacts the polygonal body side surface.

Then, when the polygonal bodies 42A and 42B stop, one side of each side becomes parallel to each other, and the apex of the side faces the cutter 49 of the cutting mechanism 48, and this cutter projects to cause the tape 3B. Disconnect. Therefore, the tape 3B changes into a piece shape, and one tape is adsorbed and held by one side portion 44.

On the other hand, the plate-shaped body 1A is transported by the transport mechanism S and is stopped when reaching between the polygonal bodies 42A and 42B. Each elevating mechanism is driven at a timing to move the polygonal bodies 42A and 42B in a direction of contacting each other. At this time, the rotation of the polygonal bodies 42A and 42B is stopped, and as described above, the predetermined side portions 4 of the polygonal bodies 4A and 42B are stopped.
4, 44 are parallel to each other.

These side portions 44, 44 are the plate-like body 1A.
Abut. The cut tape piece 3B adsorbed and held here has its adhesive surface facing the plate-like body 1A side, which is the front surface side, so that it is simultaneously attached to both surfaces of the plate-like body.

When this operation is completed, the lifting mechanism drives the polygonal bodies 42A and 42B in a direction to separate them from each other,
The plate-shaped body 1A having the tape pieces 3B attached to both sides is released. The transport mechanism again transports the plate-shaped body 1A and carries it out from between the polygonal bodies.

The polygonal bodies 42A and 42B are rotationally driven again in a predetermined direction and at a predetermined angle, and stop to make one side of each other parallel. Then, after the cutting mechanism 48 operates to cut the tape 3B, the elevating mechanism operates to bring the sides 44 of the polygonal body into contact with the plate-shaped body 1A to be conveyed next, and the tape pieces are attached to both sides thereof. Stick it. Hereinafter, this operation is repeated.

As described above, if the transport and discharge of the plate-shaped member 1A are performed in synchronization with the tape sticking action by using, for example, a rotary index device, extremely high-speed processing becomes possible.
