  In the case of sticking a label-like adhesive tape to a tape adherend by the above-described conventional tape sticking apparatus, the label-like tape attached to each of the ring frames that are the tape adherends. Adhesive tapes are separated from each other by a certain distance, and are applied to release tapes in a row, making the cut shape of the laminated tape complicated, making it cumbersome to manufacture, and reducing the number of label-like adhesive tapes. In addition to increasing the required length of the adhesive tape and release tape that make up the laminated tape, the adhesive tape portion located between the many label-like adhesive tapes is wasted and discarded together with the attached release tape portion. There are problems such as.

  The present invention was devised to solve such problems. That is, it is possible to attach a label-like adhesive tape to a ring frame, which is a tape adherend, more rationally than before. An object of the present invention is to provide a tape attaching method and an apparatus therefor.

  In order to achieve the above object, the tape adhering method according to the present invention, as described in claim 1, forms a separation assist notch for separating the longitudinal direction into a certain length at certain intervals in the longitudinal direction. The laminated tape formed by laminating the adhesive tape to the release tape is moved on the tape guide path, and the tip of the adhesive tape partially peeled from the release tape during the movement is attached to the tape. Match the start position, and then press the adhesive tape thus matched to the tape adherend positioned on the table with the tape pressing means, and then remove the adhesive tape from the release tape. The adhesive tape is attached to the tape adherend from the front end side of the adhesive tape by moving the table while being peeled, and the movement of the laminated tape is regulated during the attachment. The moving force of the serial table is performed as to separate tensile position cut separation assisting in this cutting-edge side of the adhesive tape.

  According to the tape adhering method of the present invention, the adhesive tape portion of a certain length range from the front end of the adhesive tape of the laminated tape to the cutting aid cutting position on the most advanced side is separated from the laminated tape, and the first untreated It will be in the state affixed on the tape adherend. After this, remove the tape adherend to which the adhesive tape has been attached from the table, position the second untreated tape adherend on the table, and again, when the tape attachment method of the present invention is carried out, The previously separated separation auxiliary cut position becomes the leading edge of the laminated tape, and in the same manner as above, the adhesive tape portion of a certain length range from the leading edge of the laminated tape's adhesive tape to the cutting-edge separation auxiliary cut position is It will be in the state where it was separated from the laminated tape and stuck to the second untreated tape adherend. Such treatment is performed for each of the untreated tape adherends. Therefore, the adhesive tape of the laminated tape is the one in which the entire length range of a certain length range separated at the separation auxiliary cutting position becomes a label-like adhesive tape and is attached to the tape adherend, in the length direction. A part of is not discarded without being used. Moreover, since the label-like adhesive tape portions to be attached to the tape adherend are arranged without gaps in the longitudinal direction of the adhesive tape, the label-like adhesive tape portion to be attached to each tape adherend For numbers, the length of the laminated tape is relatively short.

In order to achieve the above object, a first tape adhering device according to the present invention is, as described in claim 2, for separation assistance for separating the longitudinal direction into a certain length at certain intervals in the longitudinal direction. Tape guide moving means for moving the laminated tape formed by laminating the adhesive tape formed with the cuts on the release tape on the tape guide path, and movable in a specific direction related to the moving direction of the laminated tape The table is made to position the tape adherend on the support surface, and the adhesive tape is peeled off from the front end side of the release tape at the tape peeling portion on the tape guide path and stretched in a specific direction. was issued by pressing is stuck by the tape pressing means the adhesive tape portion of the front side to the tape pasting target body than a position cut separation assisting the leading edge side of the adhesive tape One該貼a tape applying means for separating from the laminated tape deposition process, the said adhesive tape to said tape pasting target body by the adhesive tape which moves the table while peeled from the release tape Adhesion is applied from the front end side of the adhesive tape, the movement of the laminated tape is regulated during application, and the adhesive tape is pulled and separated at the cutting-in cutting position for separation assisting by the moving force of the table.

  According to this tape sticking apparatus, the tape adhesive tape has a total length range of a certain length range separated at the separation auxiliary cutting position by the related operations of the tape guide moving means, the table, and the tape sticking means. It becomes the label-like adhesive tape part stuck on the sticking body, and it is not discarded without using a part of the length direction of the adhesive tape. If the length of the laminated tape used here is the same, the number of label-like pressure-sensitive adhesive tape parts to be attached to each tape adherend is large.

  According to the present invention, a pressure-sensitive adhesive tape having a separation assist cut formed at a fixed interval position in the moving direction is used, and therefore, the adhesive tape is attached to each of the ring frames that are tape adherends. Compared to the conventional case of using a conventional laminated tape in which a large number of label-like adhesive tape portions are adhered to a release tape in a row with a certain distance from each other in the longitudinal direction of the adhesive tape In addition, the shape of the separation auxiliary cut formed on the adhesive tape of the laminated tape is simplified and the laminated tape can be easily manufactured, and the adhesive constituting the laminated tape with respect to the number of label-like adhesive tape portions The required length of the tape and the release tape is reduced, and the material cost of the consumed laminated tape is reduced. There is no wasteful adhesive tape or release tape between the bell-shaped adhesive tape parts, so that waste of resources is avoided and sticking of the adhesive tape to the tape adherend is rational Will be able to do it.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
First, the laminated tape used with the tape sticking apparatus which concerns on this invention is demonstrated.
FIG. 1 is a top perspective view showing a laminated tape, and FIG. 2 is a partially enlarged explanatory view of the laminated tape.

  The laminated tape T is basically formed by adhering the adhesive tape T1 in a laminated form on substantially the entire surface of one side of the release tape T2. The pressure-sensitive adhesive tape T1 was adhered so that the pressure-sensitive adhesive layer was formed in the same shape on the lower surface of the tape made of a synthetic resin material, and could be relatively easily separated from the release tape T2 by the pressure-sensitive adhesive force of the pressure-sensitive adhesive layer. It is in a state.

  In the adhesive tape, separation assist notches b1 for separating the longitudinal direction f1 into a fixed length are formed at fixed intervals a1 in the longitudinal direction f1 at any stage of the manufacturing process. Here, the size of the constant interval a1 corresponds to the length of the tape adherend to which the adhesive tape T1 is attached. The separation assist notch b1 is formed by forming a single-line notch having a depth not exceeding the full length of the thickness of the adhesive tape T1 from above.

  A separation notch b2 corresponding to the shape of the ring frame w is formed on each side in the width direction of the adhesive tape T1 as necessary. The separation notch b2 is a continuous single-line notch having a depth extending over the entire thickness of the adhesive tape T1. Therefore, when the separation notch b2 is formed on the adhesive tape T1, the adhesive tape T1 is separated at the position of the separation notch b2 by having the central portion of the width of the adhesive tape T1 and separating from the release tape T2. Thus, the outer portion T1a of the separation notch b2 remains adhered to the release tape T2, and the inner portion T1b of the separation notch b2 becomes a band shape without separating the separation assisting notch b1. It comes to peel from T1. At this time, when a relatively strong pulling force in the longitudinal direction f1 is applied to the inner portion T1b, the inner portion T1b is cut and separated at the position of the separation assisting cut b1.

Next, the tape sticking apparatus according to the present invention will be described.

  In this tape peeling portion 13, after the laminated tape T having passed through the guide roller 12 has its width center range portion pressed by the lower end edge of the tape pressing member 13g, the entire width range passes through the upper surface side of the peeling plate member 13f. After being led to the front end edge and bent approximately 180 degrees here, it is led from the rear end edge to the obliquely rear-up feed driving roller 14 through the lower surface side of the peeling plate member 13f. In the process of feeding and moving the laminated tape T, when the leading end of the adhesive tape T1 with the separation notch b2 processed reaches the front edge of the peeling plate member 13f and passes therethrough, the adhesive tape T1 is In this case, the inner portion T1b is gradually peeled off from the top of the release tape T2 toward the front side while the outer portion T1a of each side edge in the width direction is left attached to the release tape T2. The inner portion T1b gradually increases in the amount of protrusion from the front end of the peeling plate member 13f forward as the feeding of the laminated tape T proceeds, and when the amount of protrusion reaches about several mm, the sensor c1 The light d1 emitted by is blocked at the tip of the inner portion T1a of the adhesive tape T1. By this interruption, the tape leading end detecting means 13d detects that the leading end of the inner portion TIa of the adhesive tape T1 has reached the reference position p3, and the feeding drive roller 14 feeds the laminated tape T in relation to the detection. Stop.

  The feed driving roller 14 is supported by the standing frame 500 so as to be rotatable about a left-right axis and is linked to an output shaft of the first stepping motor 14a. On the other hand, the pinch roller 15 is rotatably mounted on a left and right support shaft fixed to an arm member 15b that is swingable about a fulcrum shaft 15a fixed to the standing frame 500 and is elastically applied by the elastic member 15c. It is in a state of being pressed toward the feed drive roller 14 side. The laminated tape T (the release tape T2 and the outer portion T1a of the adhesive tape T1 attached thereto) after passing through the tape peeling portion 13 is disposed so as to pass between the feed driving roller 14 and the pinch roller 15. The pinch roller 15 is pressed against the peripheral surface of the feed driving roller 14, and in this state, the rotational force of the feed driving roller 14 is applied and the feed driving roller 14 is moved. As a result, the laminated tape T on the tape peeling unit 13 is fed and moved by an amount corresponding to the rotation of the feed driving roller 14.

  The tape take-up roller 17 is supported by the standing frame 500 so as to be rotatable about a left-right axis and is interlocked with the output shaft of the third servo motor 17a.

As a result, the first stepping motor 14a rotates and feeds and moves the laminated tape T again. From the time when the laminated tape T reaches the peeling plate member 13f of the tape peeling portion 13 by the feeding movement, the inner portion T1b of the adhesive tape T1 is peeled off from the tip at the front end of the peeling plate member 13f, When the front end passes through the reference position p3 and reaches the sticking waiting position p6 ′, the rotation of the first stepping motor 14a is stopped, the laminated tape T is stopped from moving, and the inner portion T1b of the adhesive tape T1 is stopped. The tip is held at the sticking waiting position p6 ′.

  In connection with the rotation stop of the first stepping motor 14a at this time, the second stepping motor 32 starts to rotate, and the table 200 is moved from the rear position p5 toward the front position p4. When the tape sticking start position p6 on the table 200 reaches just below the sticking waiting position p6 ′ by the movement, the first stepping motor 14a starts to rotate again, and the laminated tape T has the same moving speed as the table 200. It is made the size and is moved. In addition, due to the function of the first control circuit means, the peeling main part 13c and the pressing roller 33d are respectively in the upper positions in relation to the tape sticking start position p6 on the table 200 having reached just below the sticking waiting position p6 ′. It is lowered from p11, p8 to lower positions p10, p7.

  When the pressing roller 33d is lowered, the inner portion T1b of the adhesive tape T1 is pressed around the tip of the pressure tape 33d by the pressing roller 33d, and the tip is attached in a state that matches the tape attachment start position p6 of the ring frame w. After that, the inner portion T1b is continuously peeled by the rotation of the first stepping motor 14a and the second stepping motor 32 and is pulled to the front position p4 side together with the table 200. In the pulling movement process, as shown in FIG. The ring 33 is pressed against the upper surface of the ring frame w and the electric circuit boards w1, w1 by the roller 33d, and is continuously adhered.

  During such a sticking process, before the separation assist notch b1 on the foremost side of the adhesive tape T1 reaches the pressing area of the pressing roller 33d, the second control circuit means 34b allows the second servo motor 8a to function. The rotation is braked and stopped instantaneously and forcibly. Thereby, the feeding movement of the laminated tape T is stopped by the rotation stop of the tension braking return roller 8, and the table 200 is still moved to the front position p4 side by the rotation of the second stepping motor 14a under the stop state. The tension at the location of the adhesive tape T1, which is in the vicinity of the separation assist notch b1 on the foremost side of the adhesive tape T1, gradually increases, and when this reaches a certain size, the adhesive tape T1 is caused by the increased tension. Then, it is cut and separated at the position of the cutting aid b1 on the most advanced side.

  After the separation, since the table 200 moves to the front position p4 side, the inner portion T1b of the adhesive tape T1 that is currently stuck to the ring frame w is pressed to the sticking end position p9 shown in FIG. Pressed by 33d and securely attached. When the table 200 reaches the front position p4, the rotation of the second stepping motor 32 is stopped, the movement of the table 200 is stopped, and the tape peeling unit 13 and the pressing roller 33d are moved by the function of the first control circuit means 34a. They are raised to their upper positions p11, p8. Thereafter, the ring frame w and the electric circuit boards w1 and w1 attached integrally on the table 200 via the adhesive tape T1 are removed to the outside of the table 200, and then the adhesive tape T1 is applied. The ring frame w and the electric circuit boards w <b> 1 and w <b> 1 are placed on the table 200 in the same manner as before.

Then, the first switch 34c is turned on and operated to execute the second tape sticking process. As a result, the table 200 moves to the rear position p5.
Next, the third switch 34e is turned on and operated. In relation to the entering operation, the following operation is obtained by the second control circuit means 34b. That is, the first stepping motor 14a rotates by a predetermined rotation amount to the return side, The laminated tape T is displaced to the return side by a fixed distance, the tip of the inner part T1b of the adhesive tape T1 is moved to the upper side than the reference position p3, and then the first stepping motor 14a is rotated to the feed side. At this time, the displacement of the laminated tape T by a certain distance toward the return side causes a slack in the laminated tape T on the upper side of the peeling main part 13c, but the second servomotor 8a returns to the return side. The tension braking return roller 8 to which a rotational force is applied applies an appropriate tension to the laminated tape T, and the dancer roller 6 is pulled and displaced rearward by the elastic force of the elastic member 6b to apply an appropriate tension to the laminated tape T. Therefore, the slack of the laminated tape T from the precut device 4 to the tension braking return roller 8 is prevented.

  In such an operation by the second control circuit means 34b, the inner portion T1b of the adhesive tape T1 that has already been peeled off at the tape peeling portion 13 tends to adhere again to the release tape T2 on the upper side of the reference position p3. However, when the first stepping motor 14a rotates to the feed side, it is peeled again by the tape peeling portion 13, and when the tip of the inner portion T1b reaches the reference position p3, the reference position detection means 13d detects the tip, Based on the detection, the first stepping motor 14a rotates by a predetermined rotation amount set in advance from the detection time point, and the first stepping motor 14a reaches the sticking waiting position p6 ′ when the tip of the inner portion T1b related to the detection reaches the sticking waiting position p6 ′. The rotation of the motor 14a is stopped, and the tip of the inner portion T1b is held at the sticking waiting position p6 ′ as in the case of the first sticking process. .

  Thereafter, the same operation as that in the first sticking process is performed, that is, the second stepping motor 32 starts to rotate in association with the rotation of the first stepping motor 14a being stopped. Then, the table 200 is moved from the rear position p5 toward the front position p4 and the separation auxiliary cut position is separated, so that the front side portion of the pressure-sensitive adhesive tape T1 is separated from the separation auxiliary cut b1. Is pressed to the rear end by the pressing roller 33d and securely adhered. Thereafter, the above-described processing and operation are repeated, so that the same sticking process as the second tape sticking process is performed on each of the ring frames w placed on the table 200 one after another.

  When the tape adhering process is completed, the first switch 34c is turned on and operated without placing the ring frame w or the electric circuit board w1 on the table 200 moved to the front position p4. As a result, the table 200 moves to the rear position p5, and each part is ready for the next sticking process. When the work is finished in this state, the power switch of the control panel 34 is turned off.

The above embodiment can be modified as follows.

  As shown in these figures, the inner hole of the ring frame w has a planar view shape having no arc edge. The laminated tape T is obtained by adhering the adhesive tape T1 to the entire surface of one side of the release tape T2. In this connection, the precut device 4 processes only the separation assist notch b1 formed of the width direction line at every fixed interval position a1 in the longitudinal direction f1 of the adhesive tape T1. Other configurations are the same as those of the previous embodiment.

  Also in the tape adhesive device according to this modification, the adhesive tape T1 is pressed against the ring frame w by the pressing roller 33d and stuck as shown in FIG. 12, and the cutting aid b1 on the foremost side is the pressing roller. Before reaching the pressing area 33d, the rotation of the second servo motor 8a is braked and stopped, so that it is in the vicinity of the cutting aid b1 on the most advanced side, as in the previous embodiment. The tension at the location of the adhesive tape T1 is increased, and the adhesive tape T1 is cut and separated at the position of the cutting assisting cut b1 on the foremost side. After the separation, the pressure roller 33d presses the rear end of the adhesive tape T1 adhered to the ring frame w against the ring frame w, so that the adhesive tape T1 is attached to the ring frame w and the electric circuit board w1 on the table 200. , W1 is securely attached to the upper surface.

The above embodiment may be further modified as follows.
In the tape adhesive device, the pre-cut device 4 is omitted, and the laminated tape T processed in advance with both the separation notch b2 and the separation assist notch b1 or only the separation assist notch b1 is supplied to the adhesive tape T1. It can also be configured to be mounted on.
Further, the tape adherend in the present invention is not limited to the ring frame w, the electric circuit board w1, the semiconductor wafer, etc., and may be arbitrary.
