Description

Adhesive device for adhesive tape

The invention relates to a sticking device for adhesive tape

In the manufacturing process of flat panel displays such as liquid crystal displays and organic electroluminescent (EL) displays, it is necessary to mount electronic components on substrates to be bonded. The mounting is performed, for example, by temporarily crimping the electronic component through an adhesive tape to the terminal portion provided on the peripheral upper surface of the substrate, and then applying heat and pressure to perform crimping.

The bonded electronic components are, for example, integrated circuit (Integrated Circuit, IC) chips, tape carrier packages (Tape Carrier Package, TCP) or chips on film (Chip On Film, COF). TCP is a package in which chips such as ICs are mounted on a film-like film. The adhesive tape is, for example, made of anisotropic conductive film (Anisotropic Conductive Film, ACF) as a raw material, and has a width of several millimeters and a thickness of about several tens of micrometers. ACF is a film made of resin containing metal particles and has anisotropic conductivity.

In this way, the thin adhesive tape is constituted in the form of a belt-shaped member attached to the release tape. The tape-shaped member is sent out from the reel, and the tape is bonded to the substrate by pressure, and only the release tape is peeled off and discharged.

When the tape is used up due to bonding work, the belt-shaped member is manually replaced with a new belt-shaped member. Specifically, an operator (operator) performs the following operations. First, swap out the tape-empty reel for an unused reel. And a new ribbon member is drawn from the replaced unused reel. A predetermined length of adhesive tape is peeled off from the leading end of the extracted belt-shaped member, and is set in a bonding device. The reason why the tape at the leading end is peeled off in this way is to prevent the tape from adhering to the conveying rollers that hold and convey the belt-shaped member (release tape) from both sides on the downstream side of the laminating operation position in the conveying direction. etc., resulting in poor conveyance of the belt-shaped member.

Specifically, the imaging unit 18 is disposed below the belt-shaped member 2 and directly below the bonding reference position 10 , and its optical axis is perpendicular to the belt-shaped member 2 . That is, the sticking reference position 10 is included in the imaging range of the imaging unit 18, and when the slit 20 of the adhesive tape 21 enters the imaging range by the feeding of the belt-shaped member 2, the imaging unit 18 captures the belt-shaped material including the slit 20. Component 2. In addition, the optical axis of the imaging unit 18 may not be perpendicular to the belt-shaped member 2 . For example, the optical axis of the imaging unit 18 may be viewed from the conveyance direction of the belt-shaped member 2 and be obliquely at about 15° with respect to the vertical line of the belt-shaped member 2 . Furthermore, in the imaging unit 18 , the optical axis does not need to completely coincide with the bonding reference position 10 , as long as a desired portion of the belt-shaped member 2 located at the bonding reference position 10 enters the imaging range.

[control department] The control part 19 is a control device which collectively controls each part of the bonding apparatus 1. The control unit 19 can be constituted by, for example, a dedicated electronic circuit or a computer (computer) that operates according to a predetermined program. That is, regarding 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 control of the imaging unit 18, etc., the control contents are programmed and controlled by programmable logic. It is executed by a processing device such as a Programmable Logic Controller (PLC) or a central processing unit (Central Processing Unit, CPU).

FIG. 2 is a functional block diagram of the control unit 19 . As shown in FIG. 2, the control unit 19 has a bonding control unit 190, a tension mechanism control unit 191, a peeling control unit 192, a cutting control unit 193, an illumination control unit 194, an imaging control unit 195, a determination unit 196, and a transport control unit. 197.

The bonding control part 190 controls the heater and the lifting device provided in the bonding part 11, makes the heater heat the pressure head 110, and makes the lifting device lift the heated pressure head 110. The tension mechanism control unit 191 controls the elevating mechanism provided in the tension mechanism 121 to move the movable roller 121b up and down, thereby applying tension to the belt-shaped member 2 .

The peeling control unit 192 controls the moving mechanism provided in the peeling unit 15 to move the peeling bar 150 and the peeling bar 151 horizontally, thereby peeling the adhesive tape 21 pressure-bonded to the beater 112 from the release tape 22 . The cutting control unit 193 controls the lifting mechanism provided in the cutting unit 16 to raise and lower the cutter 160 .

The lighting control unit 194 controls lighting and extinguishing of the lighting unit 17 . The imaging control unit 195 controls imaging by the imaging unit 18 .

The determination unit 196 determines whether the position of the slit 20 of the adhesive tape 21 is good or not, or whether the cut surface is good or not, based on the image of the belt-shaped member 2 obtained by the imaging unit 18 . The determination unit 196 converts the image of the tape-shaped member 2 to gray scale, and detects the position of the slit 20 of the tape 21 . Then, the judging unit 196 judges whether or not the detected slit 20 is within the allowable range of the bonding reference position 10 . When the slit 20 is within the allowable range, it is judged as good, and when the slit 20 is outside the allowable range, it is judged as bad. Furthermore, the so-called grayscale refers to converting the brightness of an image into multi-level pixel values corresponding to the brightness, for example, using pixel value 0 (black) to pixel value 255 (white). conversion of 256 gray levels.

The judging unit 196 detects the half tangent line 20b as the slit 20 based on the image of the belt-shaped member 2 obtained by the imaging unit 18, and judges whether the shape of the cut surface is good or not. The shape of the cut surface of the half cut line 20 b is the shape of the cut formed by the cutter 160 when the belt-shaped member 2 is viewed from the adhesive tape 21 side. Regarding the half cut line 20b, for example, it is judged to be good when it is detected as a straight line with a large (bright) pixel value in the width direction of the belt-shaped member 2, and it is judged to be good when the portion with a large pixel value is not a straight line but inclined, or becomes If there is unevenness such as meandering or chipping, it is judged as defective.

In addition, the judging unit 196 judges whether or not the adhesive tape 21 protrudes well based on the presence or absence of the adhesive tape 21 in the front and rear regions of the bonding reference position 10 . The leading out of the adhesive tape 21 refers to setting a new supply reel 120 and placing the half tangent line 20b formed by the front end of the adhesive tape 21 that can be attached to the beginning of the substrate of the product, to the specified position including the attachment reference position 10. within range. The predetermined range is an allowable range for positioning the half tangent line 20 b at the bonding reference position 10 . The determination unit 196 may further divide each area before and after the bonding reference position 10 into a plurality of small areas to determine the presence or absence of the adhesive tape 21 .

The conveyance control unit 197 calculates the distance (offset) between the slit 20 of the tape 21 and the bonding reference position 10 when the determination unit 196 determines that the position of the slit 20 is defective. That is, when the position of the slit 20 is poor, the position of the slit 20 deviates beyond the allowable range with respect to the bonding reference position 10, and therefore the belt-shaped member 2 needs to be corrected so that the position of the slit 20 falls within the allowable range. s position. Therefore, the conveyance control unit 197 calculates the distance between the bonding reference position 10 and the position of the slit 20 based on the captured image of the imaging unit 18 , and generates a control signal for driving the feed motor based on the calculated distance. That is, the control signal is a signal for feeding the belt-shaped member 2 by the calculated distance so that the half tangent line 20b reaches the bonding reference position 10, and is output to the feeding motor.

[action] The operation|movement of the bonding apparatus 1 which has the adhesive tape 21 of the said structure is demonstrated.

[The action of sticking out the tape] FIG. 3 is a flow chart showing an example of the ejection operation of the adhesive tape 21 of the bonding apparatus 1 according to the embodiment.

Furthermore, as a premise, a new supply reel 120 is set on the supply part 12, and the strip-shaped member 2 is drawn out from the supply reel 120, and passes through the tension mechanism 121, the path roller 122, the peeling part 15, the path roller 131 and the feeder. The roller 140 is wound to the recovery reel 130 . In addition, before the tape 21 of the tape-shaped member 2 is wound, the operator peels off the downstream side, and the beginning portion 20a of the tape 21 as the slit 20 is positioned closer to the imaging unit 18, that is, the bonding reference position 10. on the upstream side. That is, the adhesive tape 21 is peeled off on the downstream side from the said opening 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 off by an operator, it is an arbitrary shape. For example, sometimes it is a line parallel to the width direction of the belt-shaped member 2, sometimes it is a line inclined with respect to the width direction of the belt-shaped member 2, and sometimes it is in a valley shape with respect to the width direction of the belt-shaped member 2. Sinuous or bumpy lines.

In addition, the beating plate 112 is placed on the support surface 111 a of the platform member 111 in advance.

As shown in FIG. 3 , the lighting unit 17 is turned on by the lighting control unit 194 , and the belt-shaped member 2 is illuminated including the bonding reference position 10 (step S01 ). As shown in (a) of FIG. 4 , the belt-shaped member 2 is sequentially fed at a predetermined pitch by the conveying unit 14 (step S02 ), and the beginning portion 20 a (slit 20 ) of the adhesive tape 21 is judged by the imaging unit 18 and the judging unit 196 . Whether the location is good or not (step S03). That is, when the belt-shaped member 2 is fed by the conveying unit 14, the imaging unit 18 takes an image of the belt-shaped member 2 within the imaging range including the lamination reference position 10, and the determination unit 196 grayscales the image obtained by the imaging unit 18, as follows: As shown in (b) of FIG. 4 , it is determined whether or not the head portion 20 a of the adhesive tape 21 is included in the predetermined range R1 including the bonding reference position 10 based on the shade difference. The portion with the adhesive tape 21 becomes dark, the portion without the adhesive tape 21 becomes bright, and the boundary between light and dark becomes the beginning portion 20a. The predetermined range R1 is, for example, an inspection area set within the imaging range.

The feed pitch of the conveyance part 14 is equal to or shorter than the length of the belt-shaped member 2 in the conveyance direction of the predetermined range R1. If the judging unit 196 does not detect the beginning portion 20a (NO in step S03 ), return to step S02 and repeat steps S02 and S03 until the beginning portion 20a is detected.

When the beginning part 20a is detected by the determination part 196 (YES in step S03), the cutting control part 193 is used to cut The tool 160 rises to cut the belt-shaped member 2 in half (step S04 ), and as shown in FIG. Then, the belt-shaped member 2 is fed by the conveyance part 14 by the distance of the cutting part 16 (cutter 160) and the bonding reference position 10 (step S05). Then, the strip-shaped member 2 is imaged by the imaging unit 18, and the presence or absence of the half-tangent line 20b is detected by the determination unit 196 (step S06). When the half tangent line 20 b is not detected (NO in step S06 ), return to step S04 .

When the half tangent 20b is detected (YES in step S06), as shown in (d) of FIG. within the allowable range (step S07). When the half tangent 20 b is not within the allowable range (NO in step S07 ), feed correction of the belt-shaped member 2 is performed. That is, the transport control unit 197 calculates the distance between the half tangent line 20b and the lamination reference position 10 based on the position of the half tangent line 20b recognized within the predetermined range R1 and the position of the lamination reference position 10 (step S08 ), and uses the transport The part 14 feeds the belt-shaped member 2 by the calculated distance so that the half tangent 20b may come to the bonding reference position 10 (step S09), and it returns to step S07.

When the half tangent line 20 b is within the allowable range (YES in step S07 ), the portion of the adhesive tape 21 from the beginning portion 20 a to the half tangent line 20 b is located between the press head 110 and the punching plate 112 . In this state, utilize the pre-heated pressure head 110 to press down the belt-shaped member 2, and the unnecessary adhesive tape 21 on the downstream side than the half-cut line 20b will be beaten on the knockout plate 112 (step S10, refer to (e) of Figure 4). That is, the preheated press head 110 is lowered by the bonding control unit 190, the unnecessary tape 21 from the head portion 20a to the half cut line 20b is bonded to the punching plate 112, and the press head 110 is raised. Then, the peeling control part 192 moves the peeling bar 150 and the peeling bar 151 horizontally to the laminating part 11 side, and the release tape 22 is peeled off from the adhesive tape 21 crimped on the beater 112 (step S11 ).

After peeling off the release tape 22, the belt-shaped member 2 is imaged by the imaging part 18 (step S12). Furthermore, since the belt-shaped member 2 is not being fed at this time, the position of the slit 20 of the adhesive tape 21 remaining upstream of the bonding reference position 10 remains unchanged at the bonding reference position 10 . The judging unit 196 converts the image obtained by the imaging unit 18 into gray scales, and sets 3 positions before and after the lamination reference position 10 as shown in (f1) and (f2) of FIG. In each of the small regions R11 to R16 serving as inspection areas, the presence or absence of the adhesive tape 21 is determined (step S13 ). The small regions R11 , R12 , R13 , R14 , R15 , and R16 at three front and rear locations are set in advance so as to be arranged side by side in the width direction of the belt-shaped member 2 . Regarding the determination of the presence or absence of the adhesive tape 21, for example, in each of the small regions R11 to R16, when the ratio of pixel points (pixels) equal to or greater than a predetermined pixel value is greater than a predetermined ratio, in other words, less than a predetermined pixel value When the ratio of pixel points 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 pixel points exceeding a predetermined pixel value is less than a predetermined ratio, in other words, it is smaller than a predetermined pixel value. When the ratio of the pixel dots is equal to or greater than a predetermined ratio, it is determined that the tape 21 is present in the small regions R11 to R16. Thus, the determination unit 196 determines whether the state (shape) of the tip (half cut line 20 b ) of the tape 21 remaining on the upstream side after peeling off the unnecessary tape 21 is good or not, thereby determining whether the tip is good or not.

As shown in (f1) of FIG. NO)), and return to step S04 as a failure. In addition, at this time, when the unnecessary tape 21 is peeled off, it is thought that a part of the tape 21 remains on the release tape 22 without peeling off, and a peeling failure occurs.

On the other hand, as shown in (f2) of FIG. 4 , when it is determined that there is no adhesive tape 21 in any of the small regions R14 to R16 located before (downstream side) the bonding reference position 10 (Yes in step S14 YES)), and it is determined that there is no adhesive tape 21 in at least any one of the small regions R11 to R13 located behind (upstream side) the lamination reference position 10 (No (NO) in step S15), it is considered that the head is defective and Return to step S04. At this time, it is conceivable that a part of the front end of the tape 21 on the upstream side of the leading tape 21 is peeled off together when the unnecessary tape 21 is peeled off. The reason for this is thought to be that the half-cut by the cutter 160 is defective, and the unnecessary tape 21 in the half-cut line 20b is connected to a part of the leading tape 21 .

Moreover, as shown in (g) of FIG. ), and it is determined that there is tape 21 in any of the small regions R11-R13 located behind (upstream side) the lamination reference position 10 (YES in step S15), it is determined that the head-out is completed and ends.

Furthermore, it is also conceivable that the following situation will repeatedly occur, that is: due to the negative (NO) determination of step S06, step S14 or step S15, it returns to step S04, and becomes negative again in the next step S06, step S14 or step S15 ( NO) judgment. In this case, the step of determining the number of repetitions can also be set before step S06 or step S14. When the set number of repetitions is repeated, it will be regarded as an error (error) and the head-out action will be interrupted, and the operator will be notified of the abnormality through an alarm (alarm) or the like. . In this case, it is conceivable that the failure of the half-cut by the cutter 160 is one cause. Therefore, the control unit 19 may also prompt to perform maintenance (maintenance) operations of cleaning or replacing the cutter 160 through an alarm.

[effect] Using FIG. 5( a ) to FIG. 8( b ), the operation of the bonding apparatus 1 according to the embodiment will be described while showing a comparative example.

(tilt of lighting section) (a) of FIG. 5 is a cross-sectional view showing the imaging status of the belt-shaped member 2 in the bonding apparatus of the comparative example. (b) of FIG. 5 is an image of the belt-shaped member 2 obtained by the bonding apparatus of the comparative example. Wherein, a graph of pixel values for each position of the image is superimposed on the image and described. The pixel value is represented by 256 gray scales where black is set to 0 and 255 is set to white.

As shown in (a) of FIG. 5 , a half mirror M is provided inside the imaging unit 18, the optical axis of the illumination L faces the half mirror M, the light of the illumination L is reflected by the half mirror M, and the light of the illumination L is The form of coaxial light parallel to the optical axis of the imaging unit 18 enters from a direction perpendicular to the belt-shaped member 2 .

As shown in (b) of FIG. 5 , there is almost no difference in pixel values between the adhesive tape 21 and the release tape 22 . Therefore, it is difficult to detect the slit 20 of the adhesive tape 21 .

It is known that it is difficult to detect the slit 20 of the adhesive tape 21 if only the lighting L is provided in this way.

(a) of FIG. 6 is a cross-sectional view showing the imaging status of the belt-shaped member 2 in the bonding apparatus 1 according to the embodiment. (b) of FIG. 6 is an image of the belt-shaped member 2 obtained by the bonding apparatus 1 of embodiment. Wherein, a graph of pixel values for each position of the image is superimposed on the image and described. The pixel value is represented by 256 gray scales where black is set to 0 and 255 is set to white.

As shown in FIG. 6( a ), the optical axis of the illuminating unit 17 is oblique to the perpendicular to the belt-shaped member 2 , and the optical axis of the imaging unit 18 is perpendicular to the belt-shaped member 2 . With such a configuration, as shown in (b) of FIG. 6 , there is a large difference in pixel values between the tape 21 and the release tape 22 , and the contrast between the portion with the tape 21 and the portion without the tape 21 becomes clear. This is presumed to be caused by the shape of the fine unevenness on the surface of the release tape 22 and the shape of the fine metal particles contained in the adhesive tape 21 . That is, the metal particles of the adhesive tape 21 are substantially spherical, and the amount of diffused light entering the imaging unit 18 does not significantly change whether the incident light from the illuminating unit 17 is coaxial or oblique. On the other hand, since the surface unevenness of the release tape 22 is random, it is presumed that the amount of diffused light entering the imaging unit 18 increases by obliquely intersecting the incident light from the illumination unit 17 . For example, in Fig. 6, the angle θ at which the optical axis of the illuminating part 17 is oblique to the vertical line of the strip-shaped member 2 is set to 75°, and the pixel value of the portion with the adhesive tape 21 is about 97, and the pixel value of the portion without the adhesive tape 21 The value becomes around 157. Thus, the density difference becomes 50 or more, and the slit 20 of the adhesive tape 21 can be detected stably.

Therefore, the inventors conducted experiments to study the relationship between the angle of the optical axis of the illumination unit 17 and the amount of light entering the imaging unit 18 . FIG. 7 shows the inclination angle θ of the optical axis of the illumination unit 17 with respect to the vertical line of the belt-shaped member 2 and the detection results of the slit 20 of the adhesive tape 21 at the angle. Furthermore, the detection result is that a white LED (model: SBR-15-50W) manufactured by Seiwa Optical Manufacturing Co., Ltd. was used as the illumination unit 17, and a camera (model: FZ-S) manufactured by Omron Corporation was used as the imaging unit 18. The result obtained by setting the distance between the belt-shaped member 2 and the imaging unit 18 to be 100 mm. In addition, as the belt-shaped member 2 to be photographed, the belt-shaped member 2 in which the slit 20 of the adhesive tape 21 is provided in parallel to the width direction of the belt-shaped member 2 is used.

As shown in FIG. 7 , change the inclination angle θ to 30°, 45°, 60°, 75°, 85°, and 90° to try to detect the slit 20 . As a result, in the cases of 30°, 45°, and 90°, the incision 20 cannot be detected well. On the other hand, when the inclination angle θ is 60°, 75°, 85°, the slit 20 can be detected well. That is, the pixel value difference between the portion with the tape 21 and the portion without the tape 21 is greater than 50, and the determination accuracy of the presence or absence of the tape 21 is improved.

In this way, by setting the inclination angle θ to 60° to 85°, it is possible to detect the beginning of the adhesive tape 21, detect the half tangent line 20b formed on the adhesive tape 21, and detect the presence or absence of the adhesive tape 21 before and after the sticking reference position 10. During the detection, the determination accuracy of the presence or absence of the adhesive tape 21 is jointly improved.

(feed correction of strip member) The feed correction of the belt-shaped member 2 will be described. As mentioned above, the distance between the cutting part 16 and the lamination reference position 10 is determined in advance, and after the half-cut line 20b is formed, the belt-shaped member 2 is fed by the distance by the conveying part 14 and the conveying control part 197. This half tangent line 20b reaches the bonding reference position 10 .

However, in practice, errors in the feed amount of the belt-shaped member 2 may occur due to rotation errors of the feed motor or the feed roller 140 or expansion and contraction of the belt-shaped member 2 . With regard to expansion and contraction of the belt-shaped member 2 , the narrower the width of the belt-shaped member 2 , the easier it is to be stretched under a certain tension, and the easier it is to get stuck on each roller or the like. Therefore, the belt-shaped member 2 may elongate inherently for each type. If an error occurs in the feeding amount of the belt-shaped member 2 in this way, the application error in the feeding direction of the tape 21 will increase.

Therefore, in the present embodiment, the imaging unit 18 and the determination unit 196 are used to determine whether the half tangent line 20b is within the allowable range of the bonding reference position 10, and when the half tangent line 20b deviates from the predetermined range, the transport control unit 197 is used to calculate the position of the adhesive tape 21. The distance between the half tangent line 20b and the bonding reference position 10 is set to a correction amount for feeding the belt-shaped member 2 by the distance so that the half tangent line 20b reaches the bonding reference position 10 . In the bonding operation described later, the belt-shaped member 2 is fed to the bonding reference position 10 by the feeding amount added with the correction amount.

That is, as shown in FIG. 8( a ), when the half tangent line 20 b is shifted to the front of the bonding reference position 10 by the feeding of the tape-shaped member 2 , the tape-shaped member 2 is bonded to the Section 11 side feed. On the other hand, as shown in FIG. 8( b ), when the half tangent line 20 b deviates beyond the bonding reference position 10 by feeding the strip-shaped member 2 , the strip-shaped member 2 is returned to the cutting portion 16 side. The mode is fed by the offset distance D2.

In this way, the deviation between the half tangent line 20b and the bonding reference position 10 is detected, and the feeding of the belt-shaped member 2 is corrected so as to eliminate the deviation, so that the adhesive tape 21 can be accurately ejected, and as a result, the The adhesive tape 21 is accurately bonded to the substrate provided in the bonding part 11 .

[fit action] FIG. 9 is a flowchart showing an example of the bonding operation of the adhesive tape 21 to the substrate by the bonding device 1 . FIG. 10 is a diagram showing the bonding operation of the bonding device 1 .

As a premise, as shown in FIG. 10( a ), the slit 20 (half cut line 20 b ) of the adhesive tape 21 is located at the lamination reference position 10 , and the tape 21 comes out. That is, the cutter 160 checks during the ejection operation that the half tangent line 20 b serving as the slit 20 is normally formed parallel to the width direction of the belt-shaped member 2 by the cutting portion 16 . In addition, the adhesive tape 21 does not remain on the downstream side of the slit 20, and the adhesive tape 21 does not adhere to members in contact with the belt-shaped member 2, such as the feed roller 140, so that conveyance failure of the belt-shaped member 2 can be prevented.

In addition, on the support surface 111 a of the table member 111 , instead of the punching plate 112 , for example, a substrate 300 for a product as a member constituting a flat-panel display is placed. Furthermore, the adhesive tape 21 is pasted on the substrate 300 with a desired length. Here, for the sake of convenience, it is assumed that the adhesive tape 21 is bonded in the entire conveyance direction of the substrate 300, and the distance between the cutting portion 16 and the bonding reference position 10 is not equal to the length of the substrate 300 and the length of the pressure head 110. equal.

As shown in FIG. 10(b), first, the belt-shaped member 2 is cut in half by the cutting unit 16 (step S21). Then, as shown in FIG.10(c), the belt-shaped member 2 is fed by the conveyance part 14 by the distance of the cutter 160 and the bonding reference position 10 (step S22). By this feeding, the half tangent line 20b formed in step S21 coincides with the bonding reference position 10 . Then, the stage member 111 is moved so that the edge portion of the substrate 300 to which the tape 21 is attached is positioned under the belt-shaped member 2 . Then, the pressure head 110 heated in advance is lowered, and the substrate 300 and the strip-shaped member 2 are clamped and bonded by the pressure head 110 and the platform member 111, and the adhesive tape 21 of the strip-shaped member 2 is pasted on the substrate 300 ( Step S23). Then, the pressure head 110 is raised, and the peeling part 15 is horizontally moved to the bonding part 11 side, thereby as shown in Figure 10 (d), the release tape 22 is peeled off from the tape 21 bonded to the substrate 300 (step S24), return the peeling part 15 to the original position.

Then, when the adhesive tape 21 is to be bonded on the substrate 300 to which the tape 21 is not bonded (YES in step S25), the bonded substrate on the platform member 111 is replaced with a new substrate to which the tape 21 is not bonded. 300, return to step S21.

On the other hand, when it is not necessary to bond the tape 21 to the substrate 300 to which the tape 21 is not bonded (No (NO) in step S25 ), the process ends. Furthermore, when feeding the band member In step S22 of 2, the same feed correction of the belt-shaped member 2 as in the above-mentioned steps S06 to S09 can be performed.

[Effect]

The sticking device 1 of the adhesive tape 21 of the embodiment includes: a supply part 12 for supplying the belt-shaped member 2 on which the tape 21 is pasted on the release tape 22; The release belt 22 is the bonding surface on the opposite side; the conveying part 14 feeds the tape-shaped member 2 from the supply part 12 to the bonding part 11; the lighting part 17 is arranged on the tape 21 side of the tape-shaped Toward the bonding reference position 10 set for the bonding part 11, and set obliquely at a preset angle with respect to the perpendicular direction of the bonding surface of the adhesive tape 21 at the bonding reference position 10; The axis is aligned with the bonding reference position 10, arranged on the tape 21 side of the tape-shaped member 2, and the tape-shaped member 2 located at the bonding reference position 10 is photographed; image to determine whether the state of the slit 20 of the tape is good or not.

Thereby, the slit 20 of the tape 21 can be automatically recognized, and therefore the tape 21 can be automatically ejected without manually ejecting the tape 21 . That is, when the illumination L is provided so that the optical axis is perpendicular to the belt-shaped member 2 as in the comparative example, the image of the belt-shaped member 2 becomes unclear, and it becomes difficult to detect the incision 20 . On the other hand, the inventors of the present invention have obtained the knowledge that the contrast of the image of the belt-shaped member 2 becomes clearer by providing the illuminating portion 17 obliquely with respect to the vertical line of the belt-shaped member 2 according to diligent research by the present inventors. . According to this embodiment based on the above knowledge, the tape 21 can be pulled out automatically.

The bonding apparatus 1 of the adhesive tape 21 of the embodiment includes a cutting unit 16 having a cutter 160 provided between the supply unit 12 and the bonding unit 11, and cutting the adhesive tape 21 of the belt-shaped member 2. Cut to form the half-cut 20b that becomes the slit 20, and the conveying unit 14 feeds the strip-shaped member 2 in such a way that the half-cut 20b arrives at the bonding reference position 10, and the imaging unit 18 photographs the strip-shaped member 2 including the half-cut 20b, The determination unit 196 detects the half tangent 20 b from the image obtained by the imaging unit 18 , and determines whether the shape of the cut surface of the half tangent 20 b is good or not.

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 assumed that the blade of the cutter 160 is worn out. At this time, for example, a display device such as a monitor or a notification means such as a speaker can be connected to the control unit 19 to prompt the operator to replace the cutter 160 on the screen or by voice.

The judging unit 196 judges whether the detected half tangent line 20 b is within the allowable range of the bonding reference position 10 .

Thereby, the alignment accuracy of the half tangent to the bonding reference position 10 can be improved.

The bonding apparatus 1 of the adhesive tape 21 according to the embodiment includes a transport control unit 197 that calculates the distance between the half tangent line 20b and the bonding reference position 10, and when the determination unit 196 determines that the half tangent line 20b deviates from the allowable range, The conveyance part 14 feeds the belt-shaped member 2 so that the half tangent 20b may be located in the bonding reference position 10 based on the distance calculated by the conveyance control part 197. FIG.

Thereby, the precision with which the tape 21 comes out can be improved, and the positional precision of the bonding|attachment of the tape 21 with respect to the board|substrate used as a bonding object in the advancing direction of the belt-shaped member 2 can be improved.

The bonding unit 11 bonds the adhesive tape 21 on the downstream side of the half-cut line 20b to the object to be bonded, specifically the beating plate 112, and the imaging unit 18 takes a picture of the tape bonded by the bonding portion 11. In the shape member 2, the judging unit 196 judges the presence or absence of the tape 21 in a plurality of regions set along the width direction of the tape 21 before and after the sticking reference position 10, and judges whether the tape 21 is good or not based on the judgment result.

Thereby, the adhesive tape 21 can be made into the state which does not remain before the sticking reference position 10, and the tape 21 exists after sticking the reference position 10, and the tape 21 can be accurately performed. In addition, it is possible to prevent conveyance failure of the belt-shaped member 2 caused by the adhesive tape 21 remaining on the release tape 22 being entangled in rollers such as the conveyance section 14 located downstream of the bonding section 11 .

The determination unit 196 grayscales the image to detect the slit 20 . Thus, not only the existence of the slit 20 can be accurately detected, but also whether the slit 20 is good or not can be accurately detected. For example, when the slit 20 is the half tangent line 20b, it is conceivable that the adhesive tape 21 is actually not completely cut due to the contamination of the tip of the cutter 160 or the blunting of the blade, and the adhesive tape 21 is thinner than the original thickness. The thinner thickness partially remains, and the half tangent line 20b looks like a dotted line. If the image is binarized, it may be falsely detected that the half tangent line 20b is normally formed. That is, the thickness of the remaining adhesive tape 21 is thin, so when the pixel value of the portion of the adhesive tape 21 is on the non-adhesive tape 21 side with respect to the binarization threshold, the detection of the half tangent line 20b is good. Even in such a case, by grayscale-grading the image, it can be detected that the adhesive tape 21 on the half-cut line 20b remains without disappearing from the image, and it can be detected that the half-cut line 20b is defective.

The illuminating unit 17 is provided with an optical axis inclined by 60° to 85° with respect to the vertical line of the belt-shaped member 2 . Thereby, the contrast of the image of the belt-shaped member 2 acquired by the imaging part 18 and the determination part 196 can be made more distinct, and the incision 20 can be detected accurately.

The illuminating unit 17 emits white light or green light. Thereby, the contrast of the image of the belt-shaped member 2 acquired by the imaging part 18 and the determination part 196 can be made more distinct, and the incision 20 can be detected accurately.

Especially when the white light or green light illuminating part 17 and the adhesive tape 21 are anisotropic conductive film, the contrast is more obvious, and the detection accuracy of the slit 20 is improved, resulting in improved accuracy of the head.

In the above-described embodiment, the illuminating unit 17 is provided on the upstream side of the belt-shaped member 2 with respect to the bonding reference position 10 , but may be provided on the downstream side of the belt-shaped member 2 as shown in FIG. 11 . At this time, after the beating of the tape 21 , the cross section of the slit 20 of the tape 21 is exposed on the side of the illuminating unit 17 , thereby directly illuminating the cross section, and the contrast of the image of the belt-shaped member 2 becomes clear. Although not limited to the following mechanism, it is conceivable that the reason is that the light reflected by the end surface of the slit 20 or the metal particles in the adhesive tape 21 is also reflected on the release tape 22 on the downstream side of the slit 20 and enters. In the imaging unit 18, the amount of received light reflected in the vicinity of the slit 20 increases.

In addition, in the above-described embodiment, the feeding amount of the belt-shaped member 2 is corrected by the conveying part 14, but it is also possible to separately provide a moving mechanism for moving the bonding part 11, and use this moving mechanism to make the bonding part 11 By moving, the bonding reference position 10 is aligned with the half tangent line 20b.

In the above-described embodiment, the lamination reference position 10 is set to coincide with the upstream end of the press head 110, but it may be set to another position, for example, closer to the upstream end of the press head 110. Position on the upstream side.

In the above-described embodiment, when a new belt-shaped member 2 is installed in the laminating device 1, the slit 20 to be the beginning portion of the adhesive tape 21 is set to an arbitrary shape formed by the operator, At this moment, the slit 20 is formed parallel to the width direction of the belt-shaped member 2 . At this time, it is only necessary for the tape 21 to be pulled out from step S01 to step S03.
