Description

Adhesive device for adhesive tapes {APPARATUS FOR ADHERING ADHESIVE TAPE}

The present invention relates to a device for bonding an adhesive tape.

In the manufacturing process of flat panel displays, such as a liquid crystal display and an organic electroluminescent display, it is necessary to mount an electronic component on the board|substrate which is an adhesion|attachment object. This mounting is performed, for example, by press-bonding an electronic component through an adhesive tape to a terminal portion provided on the upper peripheral surface of the substrate, and then applying heat and pressure to perform main compression bonding.

The electronic component to be adhered is, for example, an IC chip, a Tape Carrier Package (TCP), or a Chip On Film (COF). TCP is a package which mounted chips, such as an IC, on the thin film type. The adhesive tape is made of, for example, ACF (Anisotropic Conductive Film), a tape having a width of several millimeters and a thickness of several ten microns. ACF is a film having anisotropic conductivity made of a resin containing metal particles.

Thus, the thin adhesive tape is comprised as a tape-shaped member affixed to the release tape. The tape-like member is sent out from the reel, and after the adhesive tape is pressed against the substrate, only the release tape is peeled off and discharged.

The tape-like member was manually replaced with a new tape-like member when the adhesive tape was removed by the bonding operation. Specifically, the operator was performing the following operation. First, the reel from which the adhesive tape has disappeared is replaced with an unused reel. A new tape-like member is taken out from the replaced unused reel. The adhesive tape for a predetermined length is peeled off from the front-end|tip of the tape-shaped member which took out, and it sets in the adhesion|attachment apparatus. Peeling off the adhesive tape at the tip in this way means that the adhesive tape is attached to a conveying roller or the like that conveys the tape-shaped member (release tape) from both sides on the downstream side in the conveying direction from the bonding operation position. This is to prevent defective conveyance.

On the other hand, also in the imaging unit 18, the optical axis need not completely coincide with the bonding reference position 10, and a desired portion of the tape-shaped member 2 positioned at the bonding reference position 10 may enter the imaging range. .

[control unit]

The control unit 19 is a control device that generalizes control of each part of the bonding device 1 . The control unit 19 can be configured by, for example, a dedicated electronic circuit or a computer operating with a predetermined program. That is, for the control of the bonding unit 11 , the tension mechanism 121 , the conveying unit 14 , the peeling unit 15 , the cutting unit 16 , the lighting unit 17 , the imaging unit 18 , etc., the control contents are programmed. and is executed by a processing device such as a PLC or CPU.

And the determination part 196 determines whether the detected cut|disconnection part 20 is located in the permissible range of the adhesion|attachment reference position 10. FIG. When the cut|disconnection part 20 is contained within the permissible range, it is judged as good, and when the cut|disconnection part 20 is outside the permissible range, it is judged as defective. On the other hand, grayscale conversion refers to, for example, conversion of image brightness into multi-level pixel values according to the brightness, and is typically conversion using 256 gradations of pixel value 0 (black) to pixel value 255 (white). .

The determination unit 196 detects the half cut line 20b as the cut portion 20 based on the image of the tape-shaped member 2 obtained by the imaging unit 18 , and determines whether the shape of the cut surface is good or bad. judge The shape of the cut surface of the half cut line 20b is the shape of the cut formed by the cutter 160 when the tape-shaped member 2 is seen from the adhesive tape 21 side. The half-cut line 20b is judged good when, for example, a pixel value in the width direction of the tape-shaped member 2 is detected as a large (bright) straight line, and a portion with a large pixel value is a straight line. It is judged as defective if it is not slanted, or if it has irregularities such as meandering or cracking.

Further, the determination unit 196 determines whether or not the head derivation of the pressure-sensitive adhesive tape 21 is performed based on the presence or absence of the pressure-sensitive adhesive tape 21 in the region before and after the adhesion reference position 10 . The head derivation of the adhesive tape 21 means that a new supply reel 120 is set, and the half cut line 20b formed at the tip of the leading adhesive tape 21 capable of being adhered to the substrate to be produced is placed at the bonding reference position ( It refers to positioning within a predetermined range including 10), and the predetermined range is an allowable range, assuming that the half-cut line 20b is aligned with the bonding reference position 10 .

The conveyance control unit 197 controls the distance ( deviation) is calculated. That is, if the position of the cut portion 20 is defective, since the position of the cut portion 20 is shifted by more than an allowable range with respect to the adhesion reference position 10, so that the position of the cut portion 20 is within the allowable range It is necessary to correct the position of the tape-shaped member 2 . Then, the conveyance control part 197 calculates the distance between the adhesion|attachment reference position 10 and the position of the cut|disconnection part 20 based on the captured image of the imaging part 18, and the motor for conveyance based on the calculated distance. Generates a control signal that drives That is, this control signal is a signal for transferring the tape-shaped member 2 so that the half-cut line 20b comes to the adhesion reference position 10 for the calculated distance, and is output to the transfer motor.

That is, the adhesive tape 21 is peeled off on the downstream side of the said head part 20a, and the surface of the release tape 22 is exposed. Since the shape of the head part 20a of the adhesive tape 21 is peeled by an operator, it is an arbitrary shape. For example, it may be a line parallel to the width direction of the tape-shaped member 2 in some cases, a line inclined with respect to the width direction of the tape-shaped member 2 , or a ridge with respect to the width direction of the tape-shaped member 2 . ), it may be a meandering line or an uneven line.

In addition, on the support surface 111a of the stage member 111, the throw away plate 112 shall be arrange|positioned in advance.

As shown in FIG. 3 , the illumination unit 17 is turned on by the illumination control unit 194 to illuminate the tape-shaped member 2 including the bonding reference position 10 (step S01). As shown in Fig. 4(a), the tape-shaped members 2 are transported at a predetermined pitch by the conveying unit 14 (step S02), and adhered by the imaging unit 18 and the determining unit 196 It is determined whether the position of the head portion 20a (cut portion 20) of the tape 21 is good or bad (step S03). That is, when the tape-shaped member 2 is transported by the conveying unit 14 , the imaging unit 18 photographs the tape-shaped member 2 in the imaging range including the adhesion reference position 10 , and the determination unit Reference numeral 196 grayscales the image obtained by the imaging unit 18, and, as shown in FIG.

If the head portion 20a is not detected by the determination unit 196 (NO in step S03), the flow returns to step S02, and steps S02 and S03 are repeated until the head portion 20a is detected.

When the head portion 20a is detected by the determination unit 196 (YES in step S03), the cutting control unit 193 stops the tape-shaped member 2 at the position where the head portion 20a is detected. The cutter 160 is raised by means of a method to half-cut the tape-shaped member 2 (step S04), and as shown in FIG. A half cut line 20b is formed. Then, the distance between the cutting portion 16 (cutter 160 ) and the adhesion reference position 10 and the tape-shaped member 2 are transferred by the transfer unit 14 (step S05 ). Then, the tape-shaped member 2 is imaged by the imaging unit 18, and the presence or absence of the half-cut line 20b is detected by the determination unit 196 (step S06). If the half-cut line 20b is not detected (NO in step S06), the flow returns to step S04.

When the half-cut line 20b is detected (YES in step S06), by the determination unit 196, as shown in Fig. 4(d), the detected half-cut line 20b is set to the adhesion reference position. It is determined whether or not it is within an allowable range including (10) (step S07). When the half-cut line 20b is not within the allowable range (NO in step S07), feed correction of the tape-shaped member 2 is performed. That is, the conveyance control unit 197 controls the half-cut line 20b and the bonding reference position ( 10) The distance between them is calculated (step S08), and the tape-shaped member 2 is conveyed by the conveying unit 14 for the calculated distance so that the half-cut line 20b comes to the adhesion reference position 10 . (step S09), and the flow returns to step S07.

When the half-cut line 20b is within the allowable range (YES in step S07), the portion from the head portion 20a to the half-cut line 20b of the adhesive tape 21 is the pressing head 110 and the throwaway plate. It is located between (112). In this state, the tape-shaped member 2 is pushed down with the pressure head 110 heated in advance, and the unnecessary adhesive tape 21 downstream of the half-cut line 20b is thrown away to the throwaway plate 112 . [Step S10, see Fig. 4 (e)]. That is, by lowering the preheated pressure head 110 by the adhesion control unit 190 , the unnecessary adhesive tape 21 from the head portion 20a to the half cut line 20b is applied to the throwaway plate 112 . Adhere, and raise the pressure head 110 . Thereafter, the peeling rods 150 and 151 are horizontally moved toward the bonding unit 11 by the peeling control unit 192 to peel the release tape 22 from the pressure-sensitive adhesive tape 21 pressed against the throwaway plate 112 . (step S11).

When the release tape 22 is peeled off, the tape-shaped member 2 is imaged by the imaging unit 18 (step S12). On the other hand, at this time, since the tape-shaped member 2 is not being transported, the position of the cut portion 20 of the adhesive tape 21 remaining on the upstream side of the adhesion reference position 10 is located at the adhesion reference position 10 . remain unchanged The determination unit 196 grayscales the image obtained by the imaging unit 18, and as shown in FIGS. The presence or absence of the adhesive tape 21 is determined in each small area|region R11-R16 as a total of six test|inspection areas set at a time (step S13). The front and back three small regions R11, R12, R13 and R14, R15, and R16 are preset so as to be arranged side by side in the width direction of the tape-shaped member 2 . Determination of the presence or absence of the adhesive tape 21 is, for example, in each of the small regions R11 to R16, when the ratio of the pixels used as the predetermined pixel value or more becomes the predetermined ratio or more, in other words, it is less than the predetermined pixel value When the ratio of pixels to be used is less than a predetermined ratio, it is determined that there is no adhesive tape 21 in the small regions R11 to R16, and when the ratio of pixels to be greater than or equal to a predetermined pixel value is less than a predetermined ratio , in other words, when the ratio of pixels that are less than the predetermined pixel value is equal to or greater than the predetermined ratio, it is determined that the adhesive tape 21 is present in the small regions R11 to R16. Thereby, the determination unit 196 determines whether the state (shape) of the tip (half cut line 20b) of the adhesive tape 21 remaining on the upstream side after the unnecessary adhesive tape 21 is peeled is good or bad. Determining whether the derivation is good or bad.

The determination unit 196, as shown in Fig. 4(f1), in at least one of the small regions R14 to R16 in front (downstream side) of the adhesion reference position 10, the adhesive tape 21 If it is determined that there is (NO in step S14), the flow returns to step S04 as head derivation failure. On the other hand, in this case, it is considered that a part of the adhesive tape 21 does not peel at the time of peeling of the unnecessary adhesive tape 21, but remains in the release tape 22, and it is becoming a peeling defect.

On the other hand, as shown in Fig. 4 (f2), in the case where it is determined that there is no adhesive tape 21 in any of the small regions R14 to R16 in front (downstream side) of the adhesion reference position 10, (YES in step S14), when it is determined that there is no adhesive tape 21 in at least one of the small regions R11 to 13 behind (upstream side) behind the adhesion reference position 10 (NO in step S15); It returns to step S04 as a head derivation|leading-out failure. In this case, at the time of peeling of the unnecessary adhesive tape 21, it is considered that a part of the front-end|tip of the adhesive tape 21 of the upstream which is the front adhesive tape 21 has peeled together. As this cause, it is considered that the half-cut by the cutter 160 is defective, and the unnecessary adhesive tape 21 and a part of the adhesive tape 21 at the front are connected in the half-cut line 20b.

In addition, as shown in Fig. 4(g), it is a case where it is determined that there is no adhesive tape 21 in any of the small regions R14 to R16 in front (downstream side) of the adhesion reference position 10. (YES in step S14), when it is determined that the adhesive tape 21 is present in any of the small regions R11 to 13 behind (upstream side) behind the adhesion reference position 10 (YES in step S15); It is determined that head derivation has been performed, and the process is finished.

On the other hand, it is also considered that the NO determination in step S06, step S14, or step S15 returns to step S04, followed by repeating the NO determination again in step S06, step S14, or step S15. In such a case, the step of determining the number of repetitions may be set before step S06 or step S14, and when the set number of repetitions is performed, the head derivation operation may be stopped as an error and the operator may be notified of the abnormality by an alarm or the like. In this case, the half-cut failure by the aforementioned cutter 160 is considered as one of the causes. Therefore, you may make it the control part 19 prompt execution of the maintenance work, such as cleaning or replacing|exchanging the cutter 160, by an alarm.

[Action]

The effect|action of the adhesion|attachment apparatus 1 of embodiment is demonstrated using FIGS. 5-8, giving a comparative example.

(Inclination of lighting part)

Fig. 5 (a) is a cross-sectional view showing a photographing state of the tape-shaped member 2 in the bonding apparatus of the comparative example. Fig. 5(b) is an image of the tape-shaped member 2 obtained by the bonding apparatus of the comparative example. However, graphs of pixel values for each position of the image are described overlaid on the image. The pixel value is represented by 256 gradations in which black is 0 and 255 is white.

As shown in Fig. 5(a), a half mirror M is installed inside the imaging unit 18, and the illumination L has an optical axis directed to the half mirror M, and the illumination ( The light of L) is reflected by the half mirror M, and the light of the illumination L is incident from a direction perpendicular to the tape-shaped member 2 as coaxial light parallel to the optical axis of the imaging unit 18 . .

As shown in FIG. 5B , almost no difference was obtained in pixel values of the adhesive tape 21 and the release tape 22 . Therefore, the detection of the cut part 20 of the adhesive tape 21 became difficult.

Thus, it turns out that the detection of the cut|disconnection part 20 of the adhesive tape 21 is difficult only by simply providing the illumination L.

Fig. 6(a) is a cross-sectional view showing a photographing mode of the tape-shaped member 2 in the bonding apparatus 1 of the embodiment. Fig. 6(b) is an image of the tape-shaped member 2 obtained by the bonding apparatus 1 of the embodiment. However, graphs of pixel values for each position of the image are described overlaid on the image. The pixel value is represented by 256 gradations in which black is 0 and 255 is white.

As shown in Fig. 6(a), the optical axis of the lighting unit 17 is oblique to the perpendicular of the tape-shaped member 2, and the optical axis of the imaging unit 18 is orthogonal to the tape-shaped member 2, and there is. By configuring in this way, as shown in Fig. 6(b) , there is a large difference in the pixel values of the adhesive tape 21 and the release tape 22, and the contrast between the location with the adhesive tape 21 and the location without the adhesive tape 21 is generated. has become clear It is estimated that this originates in the shape of the fine unevenness|corrugation of the surface of the release tape 22, and the shape of the fine metal microparticles|fine-particles contained in the adhesive tape 21. FIG. That is, the metal particles of the adhesive tape 21 are substantially spherical, and the amount of the diffused light entering the imaging unit 18 does not change greatly whether the incident light from the illumination unit 17 is coaxial or intersecting. On the other hand, the unevenness|corrugation of the surface of the release tape 22 is random, Therefore, it is estimated that the quantity of the diffused light entering the imaging part 18 increased by intersecting the incident light from the illumination part 17. For example, in FIG. 6 , the angle at which the optical axis of the lighting unit 17 intersects the perpendicular of the tape-shaped member 2 is set to 75°, but the pixel value at the location where the adhesive tape 21 is located is about 97, and the adhesive The pixel value of the location without the tape 21 became about 157. In this way, the light and shade difference becomes 50 or more, and the cut part 20 of the adhesive tape 21 can be detected stably.

Then, the inventors conducted an experiment to investigate the relationship between the angle of the optical axis of the lighting unit 17 and the amount of light entering the imaging unit 18 . 7 shows the inclination angle θ of the optical axis of the illuminating unit 17 with respect to the perpendicular of the tape-shaped member 2 and the detection result of the cut portion 20 of the adhesive tape 21 at the angle. On the other hand, the detection result uses, as the lighting unit 17, a white LED (model: SBR-15-50W) manufactured by Seiwa Kogaku Seisakusho, and as the imaging unit 18, a camera manufactured by Omron Corporation ( Model: FZ-S), and the distance between the tape-shaped member 2 and the imaging unit 18 is set to 100 mm. In addition, as the tape-shaped member 2 made into the photographing object, the thing in which the cut|disconnection part 20 of the adhesive tape 21 was formed parallel to the width direction of the tape-shaped member 2 was used.

As shown in FIG. 7 , detection of the cut portion 20 was attempted by changing the inclination angle θ to 30°, 45°, 60°, 75°, 85°, and 90°. As a result, in the case of 30 degrees, 45 degrees, and 90 degrees, favorable detection of the cut|disconnection part 20 could not be performed. On the other hand, when the inclination angle (theta) was 60 degrees, 75 degrees, and 85 degrees, the favorable detection of the cut|disconnection part 20 was possible. That is, the difference of the pixel value of the location with the adhesive tape 21 and the location without the adhesive tape 21 became 50 or more, and was large, and the determination precision of detection of the presence or absence of the adhesive tape 21 improved.

In this way, the inclination angle θ is set to 60° to 85°, so that the detection of the head portion of the adhesive tape 21, the detection of the half-cut line 20b formed on the adhesive tape 21, and the bonding reference position ( Also in the detection of the presence or absence of the adhesive tape 21 before and behind 10), the determination precision of the presence or absence of the adhesive tape 21 can be improved in common.

(Feed compensation of tape-shaped members)

The feed correction of the tape-shaped member 2 is demonstrated. As described above, the distance between the cut portion 16 and the bonding reference position 10 is predetermined, and after forming the half cut line 20b, the distance is determined by the conveying unit 14 and the conveying control unit 197. min, by conveying the tape-like member 2 , the half-cut line 20b comes to the adhesive reference position 10 .

However, in reality, an error may occur in the feed amount of the tape-shaped member 2 due to a rotation error of the transfer motor or the transfer roller 140 or the expansion/contraction of the tape-shaped member 2 . The expansion and contraction of the tape-shaped member 2 is, as the width of the tape-like member 2 is narrower, it is more likely to be stretched even with a constant tension, and the jamming of each roller or the like is more likely to occur. Therefore, the tape-shaped member 2 may generate a unique elongation for each variety. In this way, when an error occurs in the feed amount of the tape-shaped member 2 , the sticking error in the feed direction of the adhesive tape 21 increases.

Therefore, in the present embodiment, it is determined by the imaging unit 18 and the determination unit 196 whether the half-cut line 20b is located within the allowable range of the adhesion reference position 10, and the half-cut line 20b ) is out of the predetermined range, the conveyance control unit 197 calculates the distance between the half-cut line 20b of the adhesive tape 21 and the adhesive reference position 10, and the distance equals the half-cut line ( The correction amount for conveying the tape-shaped member 2 by the conveying unit 14 is set so that 20b) comes to the bonding reference position 10 . In the bonding operation to be described later, the tape-shaped member 2 is conveyed to the bonding reference position 10 by the conveying amount plus the correction amount.

That is, as shown in Fig. 8 (a), when the half-cut line 20b is displaced immediately in front of the adhesion reference position 10 due to the transfer of the tape-shaped member 2, the deviation distance D1 minutes, The tape-shaped member 2 is transferred to the adhesive portion 11 side. On the other hand, as shown in Fig. 8 (b), when the half-cut line 20b is shifted beyond the adhesion reference position 10 due to the transfer of the tape-shaped member 2, the shift distance D2 minutes, the tape The mold member 2 is transferred so as to be returned to the cut portion 16 side.

In this way, since the shift between the half-cut line 20b and the adhesion reference position 10 is detected and the feed of the tape-shaped member 2 is corrected so as to eliminate the shift, the head derivation of the adhesive tape 21 is accurately performed. As a result, the adhesive tape 21 can be adhere|attached correctly with respect to the board|substrate provided in the bonding part 11.

[Adhesive action]

9 is a flowchart showing an example of the bonding operation of the adhesive tape 21 to the substrate of the bonding apparatus 1 . 10 is a view showing a bonding operation of the bonding device 1 .

As a premise, as shown in Fig. 10A, the cut portion 20 (half cut line 20b) of the adhesive tape 21 is positioned at the adhesive reference position 10, so that the adhesive tape 21 is It is assumed that the head derivation of That is, the cutter 160 has been inspected in the process of the head derivation operation, and the half-cut line 20b that is the cut portion 20 is parallel to the width direction of the tape-shaped member 2 by the cut portion 16 . It is formed normally to do so. In addition, the adhesive tape 21 does not remain on the downstream side of the cut portion 20, and the adhesive tape 21 does not adhere to the member in contact with the tape-shaped member 2 such as the conveying roller 140, so that the tape-shaped It can prevent that the member 2 becomes conveyance defect.

In addition, it is assumed that the substrate 300 for products as a member constituting the flat panel display is disposed on the support surface 111a of the stage member 111 instead of the throwaway plate 112 . On the other hand, the adhesive tape 21 is adhere|attached to the board|substrate 300 with a desired length. Here, for convenience, it is assumed that the adhesive tape 21 is adhered in the entire conveyance direction of the substrate 300, and the distance between the cut portion 16 and the adhesion reference position 10 is determined by the length of the substrate 300 and the pressure head ( 111) and the same length.

As shown in Fig. 10(b), first, the tape-shaped member 2 is cut in half by the cutting portion 16 (step S21). Then, as shown in Fig. 10(c), the distance between the cutter 160 and the adhesion reference position 10 and the tape-shaped member 2 are transferred by the transfer unit 14 (step S22). . By this transfer, the half cut line 20b formed in step S21 coincides with the bonding reference position 10 . Thereafter, the stage member 111 is moved to position the edge portion of the substrate 300 to which the adhesive tape 21 is adhered under the tape-shaped member 2 . Then, by lowering the preheated pressure head 110 , the substrate 300 and the tape-shaped member 2 are sandwiched by the pressure head 110 and the stage member 111 and pressed, and the tape-shaped member 2 is The adhesive tape 21 is adhered to the substrate 300 (step S23). Thereafter, by raising the pressure head 110 and horizontally moving the peeling part 15 to the adhesive part 11 side, the adhesive tape 21 adhered to the substrate 300 as shown in FIG. ), the release tape 22 is peeled off (step S24), and the peeling part 15 is returned to its original position.

Thereafter, when the adhesive tape 21 is adhered to the substrate 300 on which the adhesive tape 21 is not adhered (YES in step S25 ), the adhesive tape 21 is applied to the substrate on the stage member 111 . ) is replaced with a new non-adhesive substrate 300, and the flow returns to step S21.

On the other hand, when the adhesive tape 21 does not adhere|attach the adhesive tape 21 to the board|substrate 300 which is not adhered (NO in step S25), it complete|finishes. In addition, in step S22 of conveying the tape-shaped member 2, you may make it carry out the feed correction|amendment of the tape-shaped member 2 similar to the above-mentioned steps S06-S09.

[effect]

The adhesive device 1 of the adhesive tape 21 of the embodiment includes a supply unit 12 for supplying a tape-shaped member 2 to which the adhesive tape 21 is adhered to the release tape 22, and an object to be adhered, An adhesive portion 11 for adhering the adhesive surface opposite to the release tape 22 of the adhesive tape 21, and a conveying portion 14 for transporting the tape-shaped member 2 from the supply unit 12 to the adhesive portion 11; , an adhesive tape disposed on the side of the adhesive tape 21 in the tape-like member 2 , the optical axis being directed toward the adhesive reference position 10 set with respect to the adhesive portion 11 , and positioned at the adhesive reference position 10 . Adhesive tape in the tape-shaped member 2 by aligning the optical axis with the illuminating part 17 and the optical axis provided intersecting at a predetermined angle with respect to the perpendicular direction of the adhesive surface of (21) with respect to the perpendicular|vertical direction of the adhesive surface of the adhesion|attachment reference position (10) An image of the tape-shaped member 2 disposed on the (21) side and obtained by the imaging unit 18 and the imaging unit 18 for imaging the tape-shaped member 2 positioned at the adhesion reference position 10, It was made to be provided with the determination part 196 which judges the quality of the state of the cut|disconnection part 20 in an adhesive tape based on it.

Thereby, since the cut portion 20 of the adhesive tape 21 can be automatically recognized, the head of the adhesive tape 21 can be automatically drawn out without the head of the adhesive tape 21 being drawn out manually. there is. That is, in the case where the lighting unit L is installed so that the optical axis is orthogonal to the tape-shaped member 2 as in the comparative example described above, the image of the tape-shaped member 2 is not clear, and the cut portion 20 is It was difficult to detect. On the other hand, by the earnest research of the present inventors, the knowledge that the contrast of the image of the tape-shaped member 2 becomes clear by providing the illumination part 17 with respect to the repair of the tape-shaped member 2 was obtained. According to this embodiment based on this knowledge, head derivation|leading-out of the adhesive tape 21 can be performed automatically.

Having a cutter 160 installed between the supply part 12 and the adhesive part 11, and cutting the adhesive tape 21 of the tape-shaped member 2 to form a half cut line 20b that becomes the cut part 20 A cutting unit 16 is provided, and the conveying unit 14 conveys the tape-shaped member 2 so that the half-cut line 20b comes to the bonding reference position 10, and the imaging unit 18, the half-cut line The tape-shaped member 2 is imaged including 20b, and the determination unit 196 detects the half-cut line 20b from the image obtained by the imaging unit 18, and It was made to judge the quality of the shape of a cut surface.

Thereby, consumption of the cutter 160 can be managed. That is, when it is determined that the half-cut line 20b is defective, it is considered that the blade of the cutter 160 is worn out. In this case, for example, a display device such as a display or notification means such as a speaker are connected to the control unit 19 , and the operator can be prompted to replace the cutter 160 on the screen or by voice.

The determination unit 196 determines whether or not the detected half-cut line 20b is within the allowable range of the adhesion reference position 10 .

Thereby, the precision of alignment with respect to the adhesion|attachment reference position 10 of a half cut line can be improved.

It is provided with the conveyance control part 197 which calculates the distance between the half-cut line 20b and the adhesion|attachment reference position 10, When it is judged by the determination part 196 that the half-cut line 20b is out of an allowable range , the conveying unit 14 conveyed the tape-shaped member 2 so that the half-cut line 20b is located at the adhesion reference position 10 based on the distance calculated by the conveying control unit 197 .

Thereby, the precision of head derivation of the adhesive tape 21 can be improved, and the adhesion positional precision of the adhesive tape 21 to the board|substrate used as an adhesion object in the running direction of the tape-shaped member 2 is improved. can do it

The adhesive part 11 adheres the adhesive tape 21 on the downstream side of the half-cut line 20b to the adhesive object, specifically, the throw away plate 112 , and the imaging part 18 is attached to the adhesive part 11 . The tape-shaped member 2 after adhesion is photographed by the determination unit 196, before and after the adhesion reference position 10, in a plurality of areas set along the width direction of the adhesive tape 21, the adhesive tape ( 21) was judged, and it was made to judge the quality of head derivation|leading-out of the adhesive tape 21 based on this judgment result.

Thereby, the adhesive tape 21 does not remain in front of the adhesion reference position 10, but it can be set as the state in which the adhesive tape 21 is behind the adhesion reference position 10, and the head of the adhesive tape 21 is drawn out. can be done accurately. In addition, the conveyance failure of the tape-shaped member 2 due to the adhesive tape 21 remaining on the release tape 22 being curled up by rollers such as the conveying unit 14 located downstream from the bonding unit 11 can be prevented. can

The determination unit 196 grayscaled the image to detect the cut portion 20 . Thereby, not only the presence or absence of the cut part 20 but the good part of the cut part 20 can also be detected correctly. For example, when the cutting portion 20 is the half-cut line 20b, the half-cut line 20b is actually completely cut by the adhesive tape 21 due to contamination of the edge of the cutter 160 or missing teeth. It is considered that the pressure-sensitive adhesive tape 21 remains partially with a thickness thinner than the original thickness and appears as a dotted line. When this image is binarized, it may be erroneously detected that the half-cut line 20b is normally formed. That is, since the thickness of the remaining adhesive tape 21 is thin, when the pixel value of this adhesive tape 21 part is on the side without the adhesive tape 21 with respect to the binarization threshold value, the half-cut line 20b is favorable. is detected Even in such a situation, by gray-scaled the image, the adhesive tape 21 on the half-cut line 20b does not disappear from the image and remains, and it can be detected that the half-cut line 20b is defective.

The lighting unit 17 was installed so that the optical axis was inclined by 60° to 85° with respect to the perpendicular of the tape-shaped member 2 . Thereby, the contrast of the image of the tape-shaped member 2 obtained by the imaging part 18 and the determination part 196 can be made clearer, and the cut|disconnection part 20 can be detected correctly.

The lighting unit 17 irradiates white light or green light. Thereby, the contrast of the image of the tape-shaped member 2 obtained by the imaging part 18 and the determination part 196 can be made clearer, and the cut|disconnection part 20 can be detected correctly. In particular, when the white light or green light illumination portion 17 and the adhesive tape 21 are an anisotropic conductive film, the contrast becomes clearer, the detection accuracy of the cut portion 20 is improved, and as a result, the accuracy of head derivation is improved. can do it
