[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-sided tape sticking apparatus used in, for example, a thermal printer head assembling process.

[0002]

2. Description of the Related Art Conventionally, for example, a double-sided tape sticking apparatus 1 shown in FIG. 2 is known. This double-sided tape applying apparatus 1 uses a roll-shaped double-sided tape 4 provided in the thermal head assembling step and wound in a roll with a liner 3 attached to one side of a double-sided tape 2 having both sides adhesive. The double-sided tape 2 is pulled out, cut into a predetermined length, and one surface is attached to a predetermined position on an object 5 which is an aluminum heat sink, and the liner 3 is peeled off.

The double-sided tape attaching device 1
Is provided with a roll guide 6 for rotatably supporting the roll-shaped double-sided tape 4, a tape guide 7 for guiding the liner 3 of the double-sided tape 2 drawn from the roll guide 6, and an integral part of the tape guide 7. The cut base 8 includes a cut base 8, a liner winding section 9 for winding the liner 3 peeled off from the double-sided tape 2, and a rotary cutter 10 facing the cutting surface of the cut base 8. Also, facing the sticking surface orthogonal to the cutting surface of the cut base 8,
A stage 11 on which the object 5 is mounted, a stage lifting cylinder 12 for driving the stage 11 in a vertical direction, that is, a direction in which the stage 11 is brought into contact with or separated from the sticking surface, 2 and a stage drive motor 14 that moves along the longitudinal direction.

When using the double-sided tape attaching apparatus 1, first, the roll-shaped double-sided tape 4 is mounted on the roll guide 6, and the liner 3 of the double-sided tape 2 pulled out from the roll-shaped double-sided tape 4 is transferred to the tape guide. The liner 3 is wound around the cut base 8 along 7 and the liner 3 peeled off from the double-sided tape 2 is wound around the liner winding section 9. Then, the double-sided tape 2 with the liner 3 attached thereto is cut by the rotary cutter 10 at the double-sided tape cutting position P1.
Is cut off, and the leading position of the double-sided tape 2 is aligned with the double-sided tape leading position P2.

For the stage 11 on which the object 5 is mounted, a stage drive motor 14 is driven by a control system,
The object 5 is moved to the registered position, and the sticking start position on the object 5 and the double-sided tape head position P2 are aligned. Then, when the positioning is completed, the stage lifting cylinder 12 is driven to raise the stage 11, and the double-sided tape 2 is pressed against the object 5.

When the crimping of the head is completed,
The stage drive motor 14 is driven by the control system, and the predetermined length, that is, the registered double-sided tape sticking length (for example, the length set according to the type) is set to L, and the double-sided tape leading position P2 Assuming that the length of the double-sided tape 2 up to the double-sided tape cutting position P1 is A, the double-sided tape 2 is moved forward by a distance of LA. When this movement is completed, only the double-sided tape 2 is cut off by the rotary cutter 10 and the stage drive motor 14 is driven to move the object 5 forward while the remaining length A of the double-sided tape 2 is removed. Paste on the object 5. In addition, the length L that is attached to the object 5
The liner 3 is wound around a liner winding section 9 by an air motor (not shown).

Then, after the double-sided tape 2 is pasted,
The roll guide 6 is fixed with a brake (not shown), and the stage ascending cylinder 12 is driven to lower the stage 11,
The work of pasting on one object 5 is completed.

At the end of the work of sticking to the object 5, the head of the double-sided tape 2 is positioned at the head P2 of the double-sided tape in preparation for the next object 5.

[0009]

However, in the above-described conventional configuration, it is difficult to always accurately position the leading position of the double-sided tape 2 at the leading position P2 of the double-sided tape. It has a problem that it is difficult to attach the tape to an accurate position at a long length.

That is, in the roll-shaped double-sided tape 4, the roll diameter and the ease of deformation of the roll-shaped double-sided tape 4 change between the initial state and the state immediately before the end. Then, when the same pulling force is applied to the liner winding portion 9 by the air motor in each diameter state and the liner winding section 9 is wound, in the initial state, the roll-shaped double-sided tape 4 is greatly deformed, It becomes difficult to accurately adjust the head position to the double-sided tape head position P2.

Similarly, when the liner 3 wound around the liner winding section 9 is wound by applying the same pulling force to the liner winding section 9 by an air motor, the initial state in which the winding amount is small is reduced. In the state immediately before the end where the winding amount has increased, the force for pulling the liner 3 changes, and as a result, the force for pulling the roll-shaped double-sided tape 4 changes, so that the roll-shaped double-sided tape 4 is deformed. However, there is a problem that it is difficult to accurately adjust the head position of the double-sided tape 2 to the head position P2 of the double-sided tape.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a double-sided tape sticking apparatus capable of precisely sticking a double-sided tape to an object.

When using the double-sided tape applying apparatus 21, first, the roll-shaped double-sided tape 4 is mounted on the roll guide 31, and the liner 3 side of the double-sided tape 2 pulled out from the roll-shaped double-sided tape 4 is removed. Tension guide 72
, From above, and around the cut base 36 along the tape guide 35, and only the liner 3 around the first liner guide 41 and the second liner guide 42. It is sandwiched and fixed between the feed roller 43 and the second liner feed roller 44.

Then, the double-sided tape 2 provided with the liner 3
In the double-sided tape cutting position P1, only the portion of the double-sided tape 2 is cut by the rotary cutter 37, and the liner 3 is sent out by driving the liner feed control motor 46. Start position P2
Position.

On the other hand, the object 5 is mounted at a predetermined position on the stage 61 by a transfer (transferring device) from a loader (not shown). Then, the stage 61 on which the object 5 is mounted is advanced by driving a stage drive motor 64 controlled by a control system, and
Position the cut base 36 at a position facing the double-sided tape leading position P2. Further, from this state, the stage raising cylinder 62 is driven to raise the stage 61, and the leading portion of the double-sided tape 2 is pressed and adhered to the object 5.

Then, at the time when the crimping of the leading portion is completed, the cut base drive motor 39 is driven by the control system, and the cut base 36 is retracted by a predetermined dimension together with the rotary cutter 37 and the first liner guide 41. That is, the object 5 is relatively advanced.

When this movement is completed, only the double-sided tape 2 is cut by the rotary cutter 37, and the cut base drive motor 39 is driven, and the double-sided tape 2 having the remaining length A is attached to the object 5. wear.

After the application of the double-sided tape 2 onto the object 5 is completed, the liner 3 is pulled from the double-sided tape 2 adhered to the object 5 by driving the stage raising cylinder 62 to lower the stage 61. Peel off.

After that, the cut base drive motor 39 is driven to advance the cut base 36 to the position where the next double-sided tape 2 is to be pasted, and then to return.

On the other hand, the liner 3 peeled off from the double-sided tape 2 is moved while the cut base 36 is moving.
By driving the liner feed control motor 46 to rotate the first liner feed roller 43, the length of the liner 3 on which the double-sided tape 2 is stuck is sent out and collected.

In this way, the operation of attaching the double-sided tape 2 to one object 5 is completed.

Next, in the attaching step of the double-sided tape 2, in particular, the cut base 36 is moved to
The operation of the tension adjusting means 28 which senses and corrects the fluctuation of the tension force of the double-sided tape 2 when attaching the double-sided tape to the object 5 and applies a constant tension force to the double-sided tape 2 will be described.

First, when the cut base drive motor 39 is stopped, the tension guide 72 applies a constant tension force to the double-sided tape 2 by the urging force of the tension spring 73, and in this state, the tension guide 72 Stops at a position intermediate between the sensor 75 and the second sensor 76. Further, the tension spring 73 is set so that the tension force between the first sensor 75 and the second sensor 76 is constant.
And the distance between the first sensor 75 and the second sensor 76 are set.

When the cut base drive motor 39 is driven to start the application of the double-sided tape 2, the tension applied to the double-sided tape 2 increases, and the tension guide 72
Is pulled against the urging force of the tension spring 73 and moves to the second sensor 76 side. Then, when the tension guide 72 moves so as to descend to the position of the second sensor 76, the control system drives the roll motor 33 in the forward direction, and the roll guide 31, that is, the roll-shaped double-sided tape 4.
Is rotated in the forward direction to feed out the double-sided tape 2.

Conversely, when the tension guide 72 rises from the neutral position, that is, moves to the first sensor 75 side, the control system drives the roll motor 33 in the reverse direction, and the roll guide 31, that is, the roll-shaped double-sided tape 4 is rotated in the reverse direction, and the double-sided tape 2 is rewound.

As described above, according to the present embodiment, for example, the tension applied to the double-sided tape 2 is controlled with respect to the control of the double-sided tape bonding unit used in the double-sided tape bonding unit 21 in the thermal printer head assembly process. By doing so, the double-sided tape 2 with the liner 3 processed into a roll shape can be accurately adhered to an object 5 such as an aluminum radiator plate at a predetermined length and position where only the double-sided tape 2 is determined. . Further, by controlling the tension applied to the double-sided tape 2, the double-sided tape 2 can be accurately attached to an arbitrary length and position without being restricted by the thickness and hardness of the double-sided tape 2.

That is, the tension adjusting means 28 adjusts the tension applied to the double-sided tape 2 by the urging force of the tension spring 73, measures the tension applied to the double-sided tape 2, and corrects the roll guide 31 for feeding the double-sided tape 2. By driving in the opposite direction, excessive tension and slack of the roll-shaped double-sided tape 2 are prevented,
Unwind the double-sided tape 2 to the correct position and length, especially
The leading portion of the double-sided tape 2 can be accurately and accurately aligned with the double-sided tape leading position P2.

The tension adjusting means 28 can be easily realized by a structure in which the two sensors 75 and 76 detect the movement of the tension guide 72 supported by the tension spring 73.

Further, with respect to the liner feeding section 25 for collecting the liner 3 peeled off from the double-sided tape 2, the length of the double-sided tape 2 adhered during the movement of the cut base 36 is controlled by the liner-feed control motor 46. By driving and rotating the first liner feed roller 43, the liner 3 of the length to which the double-sided tape 2 is adhered is sent out and collected,
Excessive tension and slack of the double-sided tape 2 can be prevented, and the double-sided tape 2 can be accurately fed out. In particular, the leading portion of the double-sided tape 2 can be accurately positioned at the double-sided tape leading position P2.

Further, the first liner guide 41 of the tape application head section 24 allows the liner 3 to pass through the upper surface of the first liner guide 41 when the double-sided tape 2 is applied, so that the operation of applying the double-sided tape 2 is performed. The liner 3 can be reliably peeled off while performing, for example, a wide width,
Alternatively, this is effective when the double-sided tape 2 having a strong adhesive force is used.

On the other hand, when the double-sided tape 2 is applied, the liner 3 is passed through the lower surface of the first liner guide 41 so that the double-sided tape 2 is hardly peeled off from the liner 3. After pasting on 5,
When the stage 61 separates from the cut base 36, the liner 3 can be peeled off, and the double-sided tape 2 can be securely attached to the object 5. For example, when the width of the double-sided tape 2 is small, It is also effective when the adhesive strength is weak.

Further, since the cut base 36 of the tape attaching head 24 and the stage 61 of the object support 26 can be moved together, it is quicker and more accurate than a configuration in which only one of them can be moved. The double-sided tape 2 can be attached to the object.

In the above embodiment, the liner 3
Of the liner 3 between the first liner feed roller 43 and the second liner feed roller 44 for reliable feeding. However, the thickness of the liner 3 can be accurately controlled, and If control is possible, the first liner feed roller 43 that is rotationally driven by the liner feed control motor 46
For example, the winding operation can be performed directly.

Further, the tension adjusting means 28 can be integrated into the double-sided tape supply unit 23.

In the above embodiment, the thermal printer head assembling process has been described.
The present invention can be applied to a configuration in which a double-sided tape having a predetermined length is attached to an object.

In the above embodiment, the adjustment in the length direction of the double-sided tape 2 has been described. However, the stage 61 on the side of the symmetrical object support portion 26 intersects the length direction in addition to the length direction. By using the XY stage that can move in the direction, the bonding position of the double-sided tape 2 in the width direction can be adjusted.
