Description

  The present invention relates to a tape slice sticking apparatus and a tape slice sticking method for sticking an ACF tape slice (tape slice) to each of a plurality of electrode portions provided on a substrate.

  In a liquid crystal panel manufacturing operation by a liquid crystal panel manufacturing system, an anisotropic conductive film tape (ACF tape) section (tape section) called an ACF (Anisotropic Conductive Film) is provided on each of a plurality of electrode portions provided on an upper surface of a substrate. There is a tape section sticking process for sticking, and an ACF sticking apparatus as a tape section sticking apparatus is used for the tape section sticking work in this tape section sticking process.

  The ACF adhering apparatus includes a substrate holding unit for holding a substrate and an adhering head provided above the substrate holding unit, and a protective tape called a separator is attached to the adhesive surface of the ACF tape. The tape member is wound around a reel and supplied. The reel is attached to the sticking head, and the sticking head is held on the substrate holding part by cutting out an ACF tape having a length corresponding to the length of the electrode part from the tape member fed out from the attached reel as a tape slice. Affixed to the electrode part of the substrate. Some of such ACF adhering apparatuses are provided with a plurality of adhering heads (for example, Patent Document 1), and a plurality of adhering heads are used to simultaneously adhere tape sections to a plurality of electrode portions. By doing so, the production efficiency of the substrate can be improved.

  In the ACF sticking device, when the length of the ACF tape remaining on the reel has become so small that the tape slice cannot be cut out (the tape has run out), the reel that has run out of tape is removed from the sticking head. Then replace the tape with a new reel. This tape exchanging operation is performed after the tape section adhering operation by the ACF adhering apparatus is stopped, and when the tape exchanging operation is completed, the adhering operation is started again.

  Here, when multiple sticking heads are provided, each sticking head normally performs the tape slice sticking operation at an equal rate, so a new reel is attached to each sticking head at the same time. If the tape section sticking operation is started, the plurality of sticking heads run out of tape at the same time, and the opportunity to interrupt the tape section sticking operation for tape replacement is reduced.

  In the section length storage unit 40f of the control device 40, data of the length of the tape section 4s to be cut out from the ACF tape 4 (hereinafter referred to as "section length". This section length is equal to Ls). Is remembered.

  The initial remaining section number calculating unit 40g stores in the tape remaining length storage unit 40e when the reel 31 is mounted on at least one of the two sticking heads 14 (for example, mounting of the reel 31 at the time of reel replacement). The data of the remaining tape length of each reel 31 is read out, the section length is read out from the section length storage unit 40f, and the number of tape sections 4s that can be cut out from the ACF tape 4 remaining in each reel 31 is determined as “initial value”. The number of remaining intercepts is calculated and stored in the initial remaining intercept number storage unit 40h (FIG. 7).

  The head operation order setting unit 40k is calculated by the initial remaining intercept number calculating unit 40g when detecting that the reel 31 is attached to at least one of the two sticking heads 14 (initial remaining intercept number storage unit). Based on the initial remaining intercept number of each reel 31 (stored in 40h), the head operation order is set in the manner described later.

  The sticking operation counter 40m counts the number of executions of the sticking operation of the tape slice 4s for each sticking head 14.

  The remaining section number calculation unit 40p sets the initial remaining section number of each reel 31 stored in the initial remaining section number storage unit 40h as the initial remaining section number, and thereafter the pasting operation counter 40m performs pasting with the pasting head 14. Each time the operation is counted, the number of remaining intercepts is subtracted to obtain the current remaining intercept number in each sticking head 14.

  The tape remaining length calculation unit 40q counts the pasting operation of the pasting head 14 by the pasting operation counter 40m with respect to the tape remaining length of the ACF tape 4 of each reel 31 stored in the tape remaining length storage unit 40e. Every time, the length Ls corresponding to one tape section 4s is subtracted from the remaining tape length of the ACF tape 4 and stored in the tape remaining length storage unit 40e (overwrite storage, that is, update storage). Thus, the tape remaining length storage unit 40e is always in a state where the current tape remaining length of each sticking head 14 is recorded.

  Instead of the configuration in which the remaining tape length of each ACF tape 4 is stored in the reel-side memory 31m provided on the side surface of the reel 31 of the ACF tape 4 in this way, each reel 31 has an ID (identification mark). Only the described barcode may be provided, and the ID of the reel 31 and the remaining tape length may be associated with each other and stored in another data management device.

  In setting the head operation order, first, the initial remaining intercept number calculating unit 40g reads the tape remaining length of the ACF tape 4 of the reel 31 of each sticking head 14 stored in the tape remaining length storage unit 40e (FIG. 10). Step ST1), the section length stored in the section length storage unit 40f is read (Step ST2 shown in FIG. 10). At this time, the remaining tape length data read from the remaining tape length storage unit 40e is read by the reader / writer LW from the remaining tape length storage memory 31m of the reel 31 to be newly attached in the direction where the tape is exchanged among the two sticking heads 14. This data is read and written in the remaining tape length storage unit 40e, and is the data originally stored in the remaining tape length storage unit 40e for those who have not exchanged the tape.

  When the initial remaining section number calculation unit 40g of the control device 40 reads the tape remaining length of the ACF tape 4 of each sticking head 14 from the tape remaining length storage unit 40e, and reads the section length from the section length storage unit 40f. Based on the read tape remaining length and section length of the ACF tape 4 of each pasting head 14, the initial remaining section number of each pasting head 14 is calculated, and the value is stored in the initial remaining section number storage unit 40h. Store (step ST3 shown in FIG. 10).

  As described above, in this embodiment, the initial remaining intercept number calculating unit 40g of the control device 40 determines the length (tape remaining length) of the ACF tape 4 remaining on the reels 31 included in each sticking head 14 and the cutout. From the length (section length) of the tape slice 4s to be obtained, the number of tape slices 4s that can be cut out from the ACF tape 4 remaining on the reels 31 included in each sticking head 14 is calculated as the initial remaining slice count. The above-mentioned step ST3 functions as an initial remaining section number calculating means, and the above-mentioned step ST3 includes the length of the ACF tape 4 remaining on the reel 31 provided in each sticking head 14 (tape remaining length) and the tape section 4s to be cut out. From the length (section length), the number of tape sections 4s that can be cut out from the ACF tape 4 remaining on the reels 31 included in each sticking head 14 is calculated as the number of remaining sections. And it has a segment number calculation process.

  When the initial remaining intercept number calculating unit 40g calculates the initial remaining intercept number of each sticking head 14 and stores the value in the initial remaining intercept number storage unit 40h, the head operation order setting unit 40k performs the initial remaining intercept number. Based on the initial number of remaining sections of each bonding head 14 stored in the storage unit 40h, the operation sequence of the bonding heads such that the difference in the number of initial remaining sections between the two bonding heads 14 gradually decreases ( The head operation order is set (step ST4 shown in FIG. 10).

  As described above, in the present embodiment, the head operation order setting unit 40k of the control device 40 includes the initial remaining intercept number of each sticking head 14 calculated by the initial remaining intercept number calculating unit 40g which is a remaining intercept number calculating unit. Based on the above, it functions as a head operation order setting means for setting the operation order (head operation order) of the sticking heads 14 so that the difference in the number of initial remaining sections between the two sticking heads 14 is gradually reduced. In step ST4, the difference in the number of initial remaining sections between the two bonding heads 14 is gradually reduced based on the number of remaining sections of each bonding head 14 calculated in the remaining section number calculating step in step ST3. This is the head operation order setting step for setting the head operation order.

  In the setting of the head operation order performed in the head operation order setting unit 40k, for example, the result of comparing the number of remaining sections of the tape section 4s for the reels 31 of the two left and right sticking heads 14 stored in the initial remaining section number storage section 40h. The number of remaining sections of the tape section 4s of the reel 31 of the sticking head 14 (hereinafter, the right sticking head 14) located on the right side when viewed from the operator OP is the sticking head 14 located on the left side when viewed from the operator OP. When the number of remaining sections of the tape section 4s of the reel 31 of the reel 31 (hereinafter, the left-hand sticking head 14) is twice, the sticking operation of the tape slice 4s by the right-hand sticking head 14 and the left-hand sticking. The tape slice 4s sticking operation in a cycle in which the frequency of the tape slice 4s sticking operation by the head 14 is 2: 1 (that is, the consumption ratio of the tape slice 4s is 2: 1). Setting the head operating sequence to be executed (see the flowchart shown in FIG. 11 (a) or FIG. 11 (b)).

  The head operation sequence shown in the flowchart of FIG. 11A is that the tape section 4s only by the left sticking head 14 is applied after performing the sticking operation (step ST11) of the tape slice 4s by only the left sticking head 14. The tape section 4s is pasted in a cycle in which the tape section 4s is pasted (step ST13) using only the right side head 14 (step ST13). The head operation sequence shown in the flowchart of b) is the same as the attaching operation of the tape section 4s by the left attaching head 14 (step ST21) and the attaching operation of the tape section 4s by the right attaching head 14 (step ST22). After performing, the tape cutting is performed in a cycle in which the tape section 4s is adhered only by the left adhesion head 14 (step ST23). And it performs the sticking of 4s.

  Alternatively, in the above-described case, the head operation order setting unit 40k first performs the attaching operation of the tape slice 4s only by the left-hand attaching head 14 having the larger number of remaining pieces, and the two attaching heads 14 When the number of remaining sections becomes equal, simultaneous bonding by two bonding heads 14 (bonding of tape sections 4s performed by simultaneously operating two bonding heads 14) or alternate bonding by two bonding heads 14 It is also possible to set a head operation sequence (see the flowchart in FIG. 12A or FIG. 12B) for executing (attachment of the tape slice 4s performed by alternately operating the two attachment heads 14).

  The head operation sequence shown in the flowchart of FIG. 12A is performed by performing each sticking operation detected by the remaining slice number calculating unit 40p after performing the sticking operation (step ST31) of the tape slice 4s using only the left sticking head 14. Based on the current number of remaining sections in the attachment head 14, it is determined whether the number of remaining sections in the left attachment head 14 and the number of remaining sections in the right attachment head 14 are the same (step ST32). As a result, when the number of remaining sections in the left sticking head 14 and the number of remaining sections in the right sticking head 14 are not the same, the process returns to step ST21 and the tape slice by only the left sticking head 14 is used. If the number of remaining sections in the left-hand sticking head 14 and the number of remaining sections in the right-hand sticking head 14 are the same, The tape slice 4s sticking operation using only the sticking head 14 (step ST33) and the tape slice 4s sticking operation using only the right sticking head 14 (step ST34) are alternately performed (alternate sticking). Is.

  On the other hand, the head operation order shown in the flowchart of FIG. 12B is detected by the remaining section number calculating unit 40p after performing the attaching operation (step ST41) of the tape slice 4s using only the left attaching head 14. Based on the current number of remaining sections in each sticking head 14, it is determined whether the number of remaining sections in the left sticking head 14 and the number of remaining sections in the right sticking head 14 are the same (step ST42). ) As a result, if the number of remaining sections in the left sticking head 14 and the number of remaining sections in the right sticking head 14 are not the same, the process returns to step ST21 and only the left sticking head 14 is used. When the tape slice 4s is pasted, and the number of remaining sections in the left-side pasting head 14 is equal to the number of remaining sections in the right-side pasting head 14. The operation (simultaneous adhesion) of simultaneously attaching the tape slice 4s by the left adhesion head 14 (step ST43) and the tape slice 4s by the right adhesion head 14 (step ST44) is repeated. .

  When the head operation order setting unit 40k sets the head operation order as described above, the sticking operation execution unit 40b applies the tape slice 4s to each sticking head 14 according to the head operation order set in the head operation order setting unit 40k. The sticking operation is performed.

  When the sticking operation executing unit 40b of the control device 40 detects that at least one of the remaining sections of each of the two reels 31 calculated by the remaining section number calculating section 40p is “0”, the sticking head 14 is stopped, and the name of the sticking head 14 ("right sticking head", "left sticking head") that requires the operator OP to change the tape is displayed on the touch panel 48. And a message that prompts the user to perform a tape exchange operation on the sticking head 14.

  When the operator OP outputs on the touch panel 48 the name of the sticking head 14 that needs the tape exchange work and a message prompting the tape exchange work to be performed on the sticking head 14, the operator OP selects the reel 31 to be exchanged. After being removed from the sticking head 14, data of the remaining tape length of the ACF tape 4 of the reel 31 is written into the remaining tape length storage memory 31 m of the removed reel 31 using the reader / writer LW. Thereby, the tape remaining length storage memory 31m of the reel 31 removed from the sticking head 14 records the tape remaining length of the ACF tape 4 when the reel 31 is removed from the sticking head 14, and the reel When the reel 31 is removed, the tape remaining length data of the reel 31 is retained on the reel 31 (in the tape remaining length storage memory 31m), and is next attached to the same or another sticking head 14. Can be used as data necessary for setting the head operation sequence performed in the above (as described above, the configuration using the ID barcode provided on each reel 31 and the data management device can also be used). .

  Next, the execution procedure of the operation | work (tape piece sticking method) which sticks the tape slice 4s to each electrode part 3B which comprises the electrode part row | line | column 3L formed on the board | substrate 2 with the ACF sticking apparatus 1 is demonstrated. In the operation of attaching the tape slice 4s, the control device 40 first carries in the substrate 2 sent from the electrode unit cleaning device on the upstream process side by a substrate carry-in mechanism (not shown) and puts it on the upper surface of the substrate holding unit 12. Hold.

  After carrying in and holding the substrate 2, the control device 40 operates the substrate holding part moving mechanism 11 so that the electrode part row 3 </ b> L formed on the substrate 2 is located immediately above the backup stage 15, and the substrate holding part. 12 is moved to position the substrate 2. When positioning the substrate 2, the control device 40 moves the two sticking heads 14 in the X-axis direction, and is provided at both left and right ends of the board 2 by the imaging cameras 25 provided in the sticking heads 14. The mark for positioning is imaged. Then, the image recognition unit 40a recognizes the image data of the obtained positioning marks by the image recognition unit 40a, thereby obtaining the positional deviation of the substrate 2 with respect to the backup stage 15. If the positional deviation occurs, the positioning of the substrate 2 is performed. Do it again.

  After positioning the substrate 2, the control device 40 controls the operation of the two sticking heads 14, and targets each electrode part 3 </ b> B constituting the electrode part row 3 </ b> L positioned immediately above the backup stage 15. The tape section 4s is attached. In the sticking operation of the tape slice 4s, the sticking operation execution unit 40b of the control device 40 uses the sticking operation program stored in the sticking operation program storage unit 40c and the head operation order setting unit 40k according to the procedure described above. According to the set head operation order, the tape slice 4s is attached to the electrode portion 3B on the substrate 2 (each electrode portion 3B of the electrode portion row 3L provided on each of the long side and the short side of the substrate 2).

  As described above, in the present embodiment, the sticking operation execution unit 40b of the control device 40 is configured to cut the tape into two sticking heads according to the head operation order set by the head operation order setting unit 40k that is the head operation order setting means. It functions as a sticking operation execution means for performing the sticking operation of 4 s, and the sticking operation of the tape slice 4 s is applied to each sticking head 14 according to the head operation order set in the head action order setting step of step ST4. This is a step of performing the attaching operation of the section 4s.

  When the attaching operation of the tape slice 4s is completed, the control device 40 carries out the substrate 2 to the temporary pressing device on the downstream process side by a substrate carry-out mechanism (not shown). Thereby, the sticking operation of the tape slice 4s per sheet of the substrate 2 is completed.

  As described above, in the tape section 4s pasting operation using the ACF sticking apparatus 1 in the present embodiment, when the tape section 4s has been pasted on the single substrate 2 carried in, the board 2 is unloaded, In addition, the substrate 2 is newly carried in and the tape slice 4s is attached. In such an operation of attaching the tape slice 4s, when at least one of the attachment heads 14 is out of tape, a notification to that effect is given. Is made through the touch panel 48, and the operator OP replaces the tape that has run out of tape. When the tape is replaced in at least one of the pasting heads 14, the head pasting order is newly set and the pasting work of the tape slice 4s by the two pasting heads 14 is resumed. Even if there is a difference in the remaining amount of tape between the heads 14, if the pasting operation of the tape slice 4 s by the two pasting heads 14 proceeds as it is, when one pasting head 14 comes to the time for replacing the tape. Since the other sticking head 14 is also in a tape exchange time, the tape can be exchanged for the two sticking heads 14 at the same time. Therefore, the sticking operation of the tape slice 4s by the ACF sticking apparatus 1 is interrupted for the tape exchange. You only have one opportunity.

  Moreover, even if the tape is replaced for one of the pasting heads 14 for some reason before the two pasting heads 14 run out of the tape after the tape is replaced, a new one is newly used from the time of the tape replacement. Since the head sticking order is set, if the sticking work of the tape slice 4s by the two sticking heads 14 proceeds thereafter, the two sticking heads 14 are also almost simultaneously cut out of the tape, and the work is interrupted once. Thus, the tapes of the two sticking heads 14 can be exchanged.

  As described above, in the ACF sticking device 1 (and the tape slice sticking method using the ACF sticking device 1) which is the tape slice sticking device in the present embodiment, a reel is attached to at least one of the two sticking heads 14. From the length of the ACF tape 4 remaining on the reel 31 of each sticking head 14 at the time of mounting the reel to which 31 is attached (tape remaining length) and the length (section length) of the tape section 4s to be cut out The number of tape slices 4s that can be cut out from the ACF tape 4 remaining on the reel 31 of each sticking head 14 at the time of reel attachment is calculated as the initial remaining slice count, and the calculated initial residual of each sticking head 14 is calculated. Based on the number of intercepts, the operating sequence of the adhering heads 14 such that the difference in the number of initial remaining intercepts between the two adhering heads 14 becomes smaller (f) Timing), and each sticking head 14 is caused to perform the sticking operation of the tape slice 4s in accordance with the set head action order. Can be substantially matched. For this reason, the opportunity to interrupt the sticking work of the tape slice 4s is reduced, and the work efficiency of the sticking work of the tape slice 4s can be improved, and the productivity of the substrate 2 by the liquid crystal panel manufacturing system can be improved.

  Depending on the type of the ACF sticking device 1, the movable range of each sticking head 14 may be different (for example, for downsizing of the device size). There may be a case where the tape section 4s cannot be pasted with another pasting head 14 even in a place where pasting can be performed. In such a case, there are cases in which the application of the present invention must be partially removed, but even in such a case, the present invention is applied to the entire work by the ACF sticking apparatus 1. The above effects are sufficiently obtained.

  Provided are a tape section pasting apparatus and a tape section pasting method capable of improving the working efficiency by reducing the opportunity to interrupt the tape section pasting work.
